rb_node cannot be an ERR_PTR() here so I removed the misleading check.
Also I removed some more dead code at the bottom.

It looks like the code from lookup_extent_mapping() may have been 
copy and pasted into search_extent_mapping()?

This doesn't change anything.  Could you put it into linux-next?
