qcacld-3.0: Stop bus_bw timer for eSAP_STOP_BSS_EVENT

Driver unload called as part of "rmmod" which reports bug_on
in hdd_bus_bandwidth_deinit as bus_bw timer still running.
Bus_bw timer is not stopped when rmmod is issued if SAP is
enabled and any STA is connected to SAP.

Stop the bus_bw timer during unload for eSAP_STOP_BSS_EVENT
