This patch fixes several issues in security:
1) the uCode doesn't know about TKIP-MMIC failure, if uCode set
RX_RES_STATUS_BAD_ICV_MIC, it means ICV failure: drop the packet silently.
2) do not allocate room in the key table of the uCode is the set_key call
is a replacement of an old key
3) check the keyidx of the key in the uCode before removing it upon
disable_key call

The hw_key_idx inside the ieee80211_key_conf structure does
not provide all the information drivers might need to perform
hardware encryption.
This is in particular true for rt2x00 who needs to know the
key algorithm and whether it is a shared or pairwise key.
By passing the ieee80211_key_conf pointer it assures us that
drivers can make full use of all information that it should know
about a particular key.
Additionally this patch updates all drivers to grab the hw_key_idx from
the ieee80211_key_conf structure.
v2: Removed bogus u16 cast
v3: Add warning about ieee80211_tx_control pointers

This patch moves the following select's:
- RFKILL : IWLWIFI_RFKILL -> IWLCORE
- RFKILL_INPUT : IWLWIFI_RFKILL -> IWLCORE
- MAC80211_LEDS : IWL4965_LEDS -> IWLCORE
- LEDS_CLASS : IWL4965_LEDS -> IWLCORE
- MAC80211_LEDS : IWL3945_LEDS -> IWL3945
- LEDS_CLASS : IWL3945_LEDS -> IWL3945
The effects are:
- with IWLCORE=m and/or IWL3945=m RFKILL/RFKILL_INPUT/MAC80211_LEDS/LEDS_CLASS
are no longer wrongly forced to y
- fixes a build error with IWLCORE=y, IWL4965=m
might be a bug in kconfig causing it, but doing this change that is
anyway the right thing fixes it

Commit b716bb91 ("iwlwifi: Cancel scanning upon association") moved the
test of priv->vif in iwl{3945,4964}_mac_config_interface() outside of
where priv->mutex is held, but still tries to do mutex_unlock() on
return. This is clearly wrong and triggers a nasty lockdep warning when
this codepath is triggered. Fix this by removing the mutex_unlock().

This patch does 3 things
1) It removes the statistics work. The request statistics command is
sent in ASYNC mode in this flow, the mutex is uneeded, so the request
statistics function can't go to sleep. No need for a workqueue anymore.
2) iwl4965_send_statistics_request has been renamed to
iwl_send_statistics_request and moved to iwl-core.c
3) A request for statistics is sent in alive_notify, the makes the uCode
sends statistics notification periodically starting from association.

Do not use workqueue for bss_info_changed post association work.
When driver is notified of association the upper layer will be notified
right after that the association is complete. Doing the post association
work in a workqueue introduces a race condition where the upper layer may
want to make use of the association, but it is not yet complete.
