Pull up following revision(s) (requested by bouyer in ticket #1242):
sys/dev/vnd.c: revision 1.240, 1.241
As discussed in
http://mail-index.netbsd.org/tech-kern/2015/01/24/msg018339.html
don't bump v_numoutput if we need to vn_lock() the vnode before queuing
the corresponding I/O, because this may deadlock with genfs_do_putpages()
when called with the vnode locked (as can happen with fsync(2)).
Instead bump is just before the last VOP_STRATEGY(), or before calling
nestiobuf_done().
Thanks to Taylor R Campbell for review.
