Log Message:
zfs: fix deadlock with GOP_MARKUPDATE

because genfs_putpages calls GOP_MARKUPDATE with v_interlock held,
it isn't safe to wait for txg or other i/o. this is a regression
caused by a recent change.
("zfs_netbsd_gop_markupdate: actually update file timestamp")

this commit fixes it by simply dropping GOP_MARKUPDATE for zfs.
as mentioned in the commit message of the change in question,
it's redundant for putpages as we update the timestamps in
GOP_WRITE as well.

for spec/fifo, call the timestamp update logic directly,
not via GOP_MARKUPDATE.

the problem was pointed out by J. Hannken-Illjes.
he also tested this patch.
