qcacld-2.0: Integer overflow in wma_unified_link_peer_stats_event_handler
In wma_unified_link_peer_stats_event_handler a check for excess WMI
buffer is done by comparing difference between WMI_SVC_MSG_MAX_SIZE and
buffer length with size of wmi_peer_stats_event_fixed_param. In case the
buffer length is a value larger than WMI_SVC_MSG_MAX_SIZE, and as buffer
length is an unsigned integer, it causes an integer overflow and results
in a very large value, thus invalidating the check.
Change the check to compare difference of WMI_SVC_MSG_MAX_SIZE and size
of wmi_peer_stats_event_fixed_param with the buffer length which
prevents chance of integer overflow.
