ath6kl: handle probe response from P2P device in P2P GO mode
When the device is in P2P GO mode and in listen state, the correct behavior is
to see two different probe response frames - one from P2P device and the other
from GO. wpa_supplicant uses the same mechanism to send the frame in both cases
(ath6kl_mgmt_tx). For GO probe response, ath6kl needs to call
ath6kl_send_go_probe_resp (this will add only WSC/P2P IEs and the rest of the
IEs are filled in by the firmware). That was done based on the nw_type ==
AP_NETWORK which would work if P2P Device role were in a separate netdev. When
P2P Device and GO use the same netdev, ath6kl needs to use the special GO probe
response case only if SSID is longer than P2P wildcard SSID.

ath9k: decouple RX error checking for DFS
Previous RX error checking was done exclusive-or for different error
types and caused DFS pulse events to be dropped when other error
flags (e.g. CRC) were set simultaneously.
This patch decouples PHY error processing from other types and ensures
that all pulses detected by HW are accounted by the pattern detector.

mac80211: make deauth/disassoc sequence more natural
The association sequence looks (roughly) like
this now:
* set BSSID
* set station to EXIST state
* send auth
* set station to AUTH state
* send assoc
* set station to ASSOC state
* set BSS info to associated
In contrast, the deauth/disassoc sequence is
the other way around:
* clear BSSID/BSS info state
* remove station
* send deauth/disassoc
(in some cases the last two steps are reversed.)
This patch encodes the entire sequence in the
ieee80211_set_disassoc() function and changes
it to be like this, for good measure with an
explicit flush:
* send deauth/disassoc
* flush
* remove station
* clear BSSID/BSS info state

mac80211: fix sta_info_flush() return value
The comment for sta_info_flush() states
"Returns the number of removed STA entries"
but that isn't actually true. Consequently,
the warning when a station is still around
on interface removal can never trigger and
this delayed finding the timer issue the
previous patch fixed. Fix the return value
here to make that warning useful again.

mac80211: fix auth/assoc data & timer leak
When removing an interface while it is in the
process of authenticating or associating, we
leak the auth_data or assoc_data, and leave
the timer pending. The timer then crashes the
system when it fires as its data is gone.
Fix this by explicitly deleting all the data
when the interface is removed. This uncovered
another bug -- this problem should have been
detected by the sta_info_flush() warning but
that function doesn't ever return non-zero,
I'll fix that in a separate patch.
