Subject: Move matching logic out of service_reply_single function
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a069fbbd11394ec5b8a32e28ff9b6c9d8d6b07c4;p=project%2Fmdnsd.git

Move matching logic out of service_reply_single function

There is only 1 place in project calling this function with the match
argument. It's easier to add prooper condition in this place and have
service_reply_single simplified by taking 1 less argument.
