ocfs2: Update syncing after splicing to match generic version
Update ocfs2 specific splicing code to use generic syncing helper. The sync now
does not happen under rw_lock because generic_write_sync() acquires i_mutex
which ranks above rw_lock. That should not matter because standard fsync path
does not hold it either.
