tree-optimization/124578 - fix copy&pasto

The following fixes a check on vro1->opcode to properly check
vro2->opcode.  This is actually a harmless copy&paste issue since
a previous check guarnateed equality of both.  Still it's less
confusing when fixed.

	PR tree-optimization/124578
	* tree-ssa-sccvn.cc (vn_reference_eq): Consistently check
	fields from vro2.
