fuse: honor iocb sync flags on write
If the IOCB_DSYNC flag is set a sync is not being performed by fuse_file_write_iter. Honor IOCB_DSYNC/IOCB_SYNC by setting O_DYSNC/O_SYNC respectively in the flags filed of the write request. We don't need to sync data or metadata, since fuse_perform_write() does write-through and the filesystem is responsible for updating file times. Original patch by Vitaly Zolotusky.
