qcacmn: add synchronous timer stop to avoid race condition

Browse Source 
Change the qdf_timer_stop to qdf_timer_sync_cancel (synchronized
timer stop), so it can wait till previous handler is completed
and then stop/delete the timer, to avoid race condition.
Also, call this qdf_timer_sync_cancel in dp_vdev_detach_wifi3,
to be symmetry with timer start in dp_vdev_attach_wifi3.
