qcacmn: Remove repetitive logs for mem alloc failure in scan

Qdf alloc api print the log in case of alloc failure and thus
the caller doesn't need to print the error again.

Remove the repetitive logs from wlan_scan_process_bcn_probe_rx_sync
and tgt_scan_bcn_probe_rx_callback. And fix check patch errors.
