qcacld-3.0: Fix wrong kernel address access issue

qcacld-2.0 to qcacld-3.0 Propagation.

this issue is caused by the completion cancel_rem_on_chan_var missed to
be reinit and make the wait_for_completion_timeout return abnormally(
cancel_rem_on_chan_var not complete but wait_for_completion_timeout not
timeout), so cause hdd_remain_on_chan_timer failed to stop or cancel
when qcacld-2.0 driver unload, and cause this timer callback function
is called by kernel when timer expired, but this timer callback function
address is invalid after qcacld-2.0 driver unload in this case. So add
the completion cancel_rem_on_chan_var reinit before it is used by
wait_for_completion_timeout and make it timeout normally when driver
unload and make the hdd_remain_on_chan_timer stop successfully.
