nl80211: fix validation of scheduled scan info for wowlan netdetect

Browse Source 
For wowlan netdetect a separate limit is defined for the number of
matchsets. Currently, this limit is ignored and the regular limit
for scheduled scan matchsets, ie. struct wiphy::max_match_sets, is
used for the net-detect case as well.
