qcacld-3.0: Make NAN high priority than TDLS in legacy platforms

Firmware handles all NAN concurrencies in the platforms which
don't advertise the WMI service cabability
WMI_SERVICE_NAN_DISABLE_SUPPORT. Host takes care of the NAN
concurrency if the capability is advertised by firmware.
But there can be some legacy targets where firmware wants to
offload NAN+TDLS concurrency alone to the host and it takes care
of rest of the concurrencies. This is to make NAN of higher
priority and disable TDLS when NAN is active. Currently, TDLS is
of more priority than NAN and it can't change the order as it
can't disable TDLS to change the priority.

Currently, driver doesn't parse the NAN messages(even NAN enable
request) in such platforms. Parse the NAN messages and disable
TDLS upon NAN enable request. Rely on NAN state machine to
allow/disallow new TDLS requests. This needs NAN enable status.
