f2fs: fix f2fs_ioc_abort_volatile_write
There are two rules to handle aborting volatile or atomic writes. 1. drop atomic writes - we don't need to keep any stale db data. 2. write journal data - we should keep the journal data with fsync for db recovery. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
