wlan: Send proper channel list to supplicant in case of setband

Added logic to send proper channel list to supplicant
in case of setband and keep wiphy and nvtable in sync
during setband. Disable social channel in case of
5GHz band which indirectly disable P2P in case
of 5GHz band.

wlan:Fix kernel panic while TDLS exit.

As a part of  TDLS exit, tdls context is freed without
explicitly setting tdls adapter as NULL. As a result, a
race condition may arise when tdls exit is called immediately
after tdls init. As a part of tdls init, driver start timers
for peerDiscovery which use tdls adapater . Since as part of tdls
exit, adapters are not set as null but are freed, timer function
might end up using memory which is freed.

As a part of fix, explicitly set adapter as null as part of tdls
exit.
