qcacmn: Delete WDS AST entry if the hw_peer_id is invalid in peer map

Delete WDS AST entry if the hw_peer_id is invalid in peer map
in cases where the HW exceeds the max hash skid it can support
the AST entry will not be added and as an indication of this
the host will receive a peer map event with hw_index as 0xffff
Host has to check for this type of hw_index and appropriately
delete the AST entry from the HOST table.
