Revive Haiku build

See merge request STJr/SRB2!2537

This was added by the Doom developers to work around the issue where
objects were not linked into all blockmap cells they were touching, and
instead just the one at the object's center. Since this is no longer
the case after commit 41613d89,
this adjustment is no longer necessary.

There was no reason to do what I did, since the loop only needs to hold
a reference to the next block. This reverts the function to how it was
before 7469a627, but holds the
reference properly.
