Revert "FIXED: CLP(B): Delay BDD restriction until after the instantiation."

This reverts commit e185b626bd.

This change is now no longer needed, and the underlying issue is
apparently somewhere else entirely. See the description at:

    https://github.com/mthom/scryer-prolog/issues/2732

Current master behaves differently from Scryer as it was at
099d9aaca6 (i.e., preceding
the commit that is now being reverted), even on the same file.

For an example, see:

    dd41176b97

Scryer now works as expected, and compatibly with SICStus. We still
need to find out what fixed the root cause of this issue.
