Log:
SVN rev 183265 on 2008-09-22 06:44:03Z by rwatson
When invoking the udp_send() from udp6_send() due to use of a v6-mapped
IPv4 address, first drop the udbinfo and inpcb locks, which will otherwise
be recursed. This leads to a potential minor race, but is preferable to a
deadlock when acquiring a read lock after a write lock on the inpcb.
