qcacmn: Destroy the queue_kicker work which is triggered by RPM resume

There might be a race condition between htc_kick_queues which is sheduled
by RPM resume and hdd_wlan_stop_modules.

Here are detail info:
1. Run time resume is called, which will schedule a work to do the
   htc_kick_queues later.
2. hdd_wlan_stop_modules is called at the same time, which will call
   htc_destroy to free the HTC_TARGET.
3. the htc_kick_queues will access the HTC_TARGET, but it has been
   freed.
