qcacmn: Free scan request if netdev is NULL or get vdev ref fails

Browse Source 
Currently driver just cancels the scan request and does not free
scan request memory if netdev is NULL or get vdev ref fails,
which leads to memleak.

To address abobve issue, free the scan request if netdev is NULL
or if get vdev ref fails.
