qcacld-3.0: Do input validation for beacon interval in packet capture mode

Beacon interval set from the vendor command in packet capture mode
should be greater than connected AP's beacon interval otherwise it
nth beacon value will be calculated as 0. So add a condition to
validate the value of user configured beacon interval before sending
it to firmware. Reject the connected beacon interval configuration in
packet capture mode if its value is not 0 and less than AP's beacon
interval.
