anon-inodes use open coded atomic_inc for the shared inode
Since we know the shared inode count is always >0, we can avoid igrab() and use an open coded atomic_inc(). This also fixes a bug noticed by Yan Zheng <yanzheng@21cn.com>: were checking for an IS_ERR() return from igrab(), but it actually returns NULL on error.
