qcacld-2.0: Fix timer leak issue in tsf

The capture tsf request timer will be deleted when the timer timeout
or receive the tsf event. So if unload wlan driver before timer
timeout or receive the tsf event, the timer will not be destory.

This change will destory capture tsf request timer when wlan driver
unload.
