Fix hostapd segfault on beacon hint event

Commit 795baf773f6d53bae3cfae4df6edda63e5022344 ('hostapd: Filter
channel list updated events after country code change') uses the
EVENT_CHANNEL_LIST_CHANGED data pointer, but it updated only one of the
callers to provide that data. NL80211_CMD_REG_BEACON_HINT event was
still sending the event without the initiator data and resulted in NULL
pointer dereference, e.g., if a scan was run while hostapd was running
and the driver was in world roaming state and enabled a channel for
active scans.

P2P: Refrain from performing extended listen during P2P connection.

Do not perform extended listen period operations when either a P2P
connection is in progress. This makes the connection more robust should
an extended listen timer trigger during such an operation.

P2P: Refrain from performing extended listen during PD

Extend the previous commit 0f1034e3889e7b8f54ed59317f1234db8167d12e to
skip extended listen also based on ongoing provision discovery operation
(which does not show up as a separate P2P module state and as such, was
not coveraged by the previous commit).

WNM: Add debug logs to get the RSSI from the scan results

This commit adds few more debug prints to log the RSSI information from
the scanned BSSIDs and the current connected BSSID when comparing
neighbor results during WNM Transition Management Request processing.

WNM: Check wpa_s->current_bss more consistently

The scan result comparison routine would not make much sense without
current BSS level known, so return from the function without going
through the iteration that could have dereferenced the pointer if
wpa_s->current_bss == NULL.
