[PATCH 02/10] ext4: set SB_I_OVL_USE_SYNC_FS if there is a journal

[Josef Bacik <josef@toxicpanda.com>]

With a journal every change of metadata is part of a transaction, and
ext4_sync_fs() commits the running one.  ext4_write_inode() has nothing to
add to that, it only forces a commit as well.

Without a journal the flag stays clear.
