Currently, driver allows VDEV-RESTART on SAP interface in order to
channel switch or hidden ssid connection when roaming is in progress
on STA interface. This leads to two simultaneous vdev starts or
vdev-restart in FW which causes the FW to assert.
Add changes to reject the channel switch for SAP or in hidden ssid
connection if roaming is in progress on any STA interface.
