[SystemZ] Fix matching another pattern for nxgrk (PR44496)

SystemZDAGToDAGISel::Select will attempt to split logical instruction
with a large immediate constant. This must not happen if the result
matches one of the z15 combined operations, so the code checks for
those. However, one of them was missed, causing invalid code to
be generated in the test case for PR44496.
