Fixed MCHit->Pixel associator issue in VPClusterEffSimDQ
The MCHit to VPChannelID linker table sets the high bits in integer representing the the VPChannelID while the VPCluster list of associated pixels does not so they stopped matching (this is a change from previous behaviour). This fix uses the pixel only bits in VPChannelID. This restores the code functionality. This requires the change in VPChannelID Detector!662 to work.
