zonefs: set FMODE_CAN_ODIRECT instead of a dummy direct_IO method

Since commit a2ad63daa88b ("VFS: add FMODE_CAN_ODIRECT file flag") file
systems can just set the FMODE_CAN_ODIRECT flag at open time instead of
wiring up a dummy direct_IO method to indicate support for direct I/O.
Do that for zonefs so that noop_direct_IO can eventually be removed.
