qcacld-3.0: Return success for stop_bss while SAP is in stopping state

If the SAP is already in stopping state and wlansap_stop_bss is invoked
as a part of stop_adapter, it returns error which causes the
stop_adapter not to wait for the vdev to return to proper state.

To avoid this, return success in case of SAP_STOPPING for the event
eSAP_HDD_STOP_INFRA_BSS
