qcacld-2.0: Fix a issue of slow QRF WoW reconnection

This change add a process in apfind_evt handler to trigger host to
reconnect to remote AP when firmware notifies host about finding this
missing AP during QRF scan.
Without this fix, host driver may take longer time to realize that
the remote AP's connection was dropped and need reconnection, since
it just wakes up from suspend and does not aware of the connection
status change.
