qcacld-3.0: Use hdd netdev notifier call for softAP interface

Browse source 
qcacld-2.0 to qcacld-3.0 propagation

In softAP scenario, if any pending scan request is not serviced
before NETDEV_GOING_DOWN is called, it results in call trace
Handle this by using hdd netdev notifier call for softAP, where
scan_block_work is flushed.
