Luiz Augusto von Dentz 91f48261e7 Bluetooth: hci_event: Fix using memcmp when comparing keys
[ Upstream commit b541260615f601ae1b5d6d0cc54e790de706303b ]

memcmp is not consider safe to use with cryptographic secrets:

 'Do  not  use memcmp() to compare security critical data, such as
 cryptographic secrets, because the required CPU time depends on the
 number of equal bytes.'

While usage of memcmp for ZERO_KEY may not be considered a security
critical data, it can lead to more usage of memcmp with pairing keys
which could introduce more security problems.

Fixes: 455c2ff0a5 ("Bluetooth: Fix BR/EDR out-of-band pairing with only initiator data")
Fixes: 33155c4aae52 ("Bluetooth: hci_event: Ignore NULL link key")
