qcacld-3.0: Add check for num_peers in wma_ibss_peer_info_event_handler

in wma_ibss_peer_info_event_handler, the driver has a upper
bound check on num_peers and not a lower bound check.
the num_peers should be a positive value.
Since there is no check to see if num_peers is set to 0,
this check can underflow and result in multiple OOB writes
once the loop has incremented more than 32 times.

Fix is to check whether num_peers is a positive value,
and return if not found true.
