[PATCH RFC v3 11/14] ext4: drop mmb_sync() from ext4_evict_inode()

[Christian Brauner <brauner@kernel.org>]

evict() writes out what I_METADATA_WRITEBACK tracks before it calls
->evict_inode() and since mmb_mark_buffer_dirty() sets the bit that
includes the tracked metadata buffers. So there's nothing left for
ext4_evict_inode() to sync without a journal, and with a journal there
are no tracked buffers.
