[SCIP] Binding SCIP 3.2.0 with cplex 12.4

[Gerald Gamrath]

Hi Abdelkader,

Cplex introduced a return value for SCIPlpiChgObjsen() in the 12.5 
release while in the 12.4 version, it was still a void function.

It seems like we updated the lpi and check the return value, but did not 
notice that there was no return value before. If you want to compile 
SCIP with an older Cplex version, please remove the CHECK_ZERO() call 
around the call of CPXchgobjsen(). This will also be fixed in the bugfix 
release coming soon.

Best,
Gerald
