This patch fixes a bug in association flow. As soon as RXON with assoc bit
is sent, uCode expects to have an entry in its station table that describe
the AP. Receiving a beacon from an HT AP before sending ADD_STA results a
uCode error. This patch sends first the ADD_STA (bcast and bssid) and only
then RXON with assoc bit set

This patch makes the station table maintenance safer. Two flags are

1) if station is present in driver
2) if station is present in uCode
This will allow us in the future to deal with more stations than the

This fixes a circular locking dependency in the workqueue handling.
The interface work task uses the mac80211 function
ieee80211_iterate_active_interfaces() which grabs the RTNL lock.
However when the interface is brough down, this happens under the RTNL
lock as well, this causes problems because mac80211 will flush the workqueue
during the ifdown event. This causes mac80211 to wait until the driver has
completed all work which can't finish because it is waiting on the RTNL lock.
This is fixed by moving rt2x00 workqueue tasks on a different workqueue,
this workqueue can be flushed when the ieee80211_hw structure is removed
by the driver (when the driver is unloaded) which does not happen under the
RTNL lock.

When rt2x00queue_alloc_rxskbs() fails rt2x00queue_unitialize()
will be called which will free all rxskb. So we don't need
to do this in the rt2x00queue_alloc_rxskb() function as well.
rt2x00queue_free_skb() unmaps the DMA but doesn't clear the
allocation flag. Since the code is copied from rt2x00queue_unmap_skb()
anyway (and that function does clear the flag) we might as well
use that function directly.
