qcacld-3.0: stop the bus bw timer during the driver unload

Browse Source 
When the driver unload is triggered, the device could be in the
runtime suspend state, so the 1st thing driver does to do runtime
resume, During this runtime resume the bus bw timer could be started
which in some race conditions is not getting stopped.

Stop the bus bandwidth timer after the wlan chip is runtime resume.
