vmstat: make vmstat_update deferrable
Commit 0eb77e988032 ("vmstat: make vmstat_updater deferrable again and
shut down on idle") made vmstat_shepherd deferrable. vmstat_update
itself is still useing standard timer which might interrupt idle task.
This is possible because "mm, vmstat: make quiet_vmstat lighter" removed
cancel_delayed_work from the quiet_vmstat.
Change vmstat_work to use DEFERRABLE_WORK to prevent from pointless
wakeups from the idle context.
