Log Message:
zfs_netbsd_gop_markupdate: actually update file timestamp

the implementation before this commit was basically no-op.

some notes:

* this is (ab)used in zfs_netbsd_write for fifo/spec vnodes.
  i feel it's a bit excessive to update the timestamp on every
  writes to /dev/null. unfortunately, zfs doesn't have nodevmtime
  option. well, i suspect netbsd is the only os with the traditional
  devmtime behavior these days. we may want to implement delayed
  mtime update as ffs does.

* this is used by zfs_netbsd_putpages via genfs_putpages. but it's
  redundant because zfs_putapage updates the timestamp as well.

* this is not used by zfs_netbsd_getpages. zfs doesn't use
  genfs_getpages. zfs_netbsd_getpages doesn't have the
  corresponding logic either. maybe it's ok for most of applications
  as far as mtime will be updated sooner or later.
