qcacmn: Use QDF sleep instead of wait_for_timeout in cancel scan

Browse source 
In the function ucfg_scan_cancel_sync the driver uses
qdf_wait_single_event to wait for the scan event to be cancelled.
This timer is affected by the timer multiplier which causes unwarranted
wait times.

Replace the qdf_wait_single_event with a simple qdf_sleep.
