As spotted by Coverity, the calculation of ojrelid mixes signed and unsigned types causes possible overflow and undefined behavior. Instead of trying to fix the expression, this commit eliminates the relied local variable. The explicit branching is used to replace the -1 value. That, in turn, requires changing the signature of the remove_rel_from_eclass() function.
