Log Message:
Pull up following revision(s) (requested by maxv in ticket #1288):
sys/netinet6/udp6_usrreq.c: revision 1.147
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.
