Patch to drop and re-aquire lock
Discussed in freebsd-wireless, here:
https://lists.freebsd.org/pipermail/freebsd-wireless/2016-December/007391.html
FreeBSD 11.0 occasionally hangs during boot due to a LOR between if_lagg.c and
if_re.c. The attached patch drops one of the locks in if_lagg.c before calling
the lower driver's initialization, then re-acquires the lock after.
