reiserfs should use mark_inode_dirty during reiserfs_file_write and
reiserfs_commit_write.  This makes sure the inode is properly flagged as
dirty, which is used during O_SYNC to decide when to trigger log commits.

This patch also removes the O_SYNC check from reiserfs_commit_write, since
that gets dealt with properly at higher layers once we start using
mark_inode_dirty.

Thanks to Hifumi Hisashi <hifumi.hisashi@lab.ntt.co.jp> for catching this.
