CVS commit: src/sys/netinet6

["Maxime Villard" <maxv%netbsd.org@localhost>]

Module Name:    src
Committed By:   maxv
Date:           Mon Feb 25 07:31:32 UTC 2019

Modified Files:
        src/sys/netinet6: udp6_usrreq.c

Log Message:
Fix the order in udp6_attach: soreserve should be called before
in6_pcballoc, otherwise if it fails there is still a PCB attached, and
we hit a KASSERT in socreate. In !DIAGNOSTIC this would have caused a
memory leak.

By the way I find the splsoftnet highly suspicious, in6_pcballoc already
does that.
