In ocfs2_remove_inode_range(), there is a memory leak.
The variable path has allocated memory with ocfs2_new_path_from_et(), 
but it is not free.

This patch looks good to me.

Reviewed-by: Jie Liu <jeff.liu@oracle.com>

BTW, I found another similar problem at: ocfs2/move_extent.c->__ocfs2_move_extent()
with a simple `grep` against the source tree, will post a patch to fix it, would
you like to help review?

Thanks,
