SCAN-OFFLOAD: Adding separate SME queue for scan commands.
In concurrent scenarios when scan is issued from the host, the FW will
do the split the scan. In this case the scan is going to take huge time
to complete. Adding a separate SME to queue for scan commands, to avoid
the blocking the SME sme command active list till scan gets complete.
