In ocfs2_mknod(), if error occurs after dinode successfully allocated,
ocfs2 i_links_count will not be 0.
So even though we clear inode i_nlink before iput in error handling, it
still won't wipe inode since we'll refresh inode from dinode during inode
lock. So just like clear inode i_nlink, we clear ocfs2 i_links_count as
well. Also do the same change for ocfs2_symlink().
