Govind Singh 3ba23ea33f qcacmn: Remove unnecessary locking during WMI detach 
HOST driver unload sequence does following
   1) Kill WLAN tasklet
   2) Disable CE interrupts
   3) Flush WMI RX work
Hence its unncessory to acquire eventq_lock as no one
will be using the shared resource during wmi detach.
