qcacld-3.0: Drop duplicate Beacon Report request

Browse source 
Currently, driver does not check for duplication of rrm
request. If driver receives any duplicate rrm request,
then driver sends pilot frame for second rrm request which
is not acceptable.
Add changes to drop all duplicate rrm requests to fix this.
