wifi: iwlwifi: mvm: fix potential out-of-bounds read in iwl_mvm_nd_match_info_handler()
The memcpy function assumes the dynamic array notif->matches is at least
as large as the number of bytes to copy. Otherwise, results->matches may
contain unwanted data. To guarantee safety, extend the validation in one
of the checks to ensure sufficient packet length.
