[PULL 21/24] target/s390x/tcg/mem_helper: Remove bad assert() statement

[Thomas Huth <thuth@redhat.com>]

The "assert(!nonfault)" statement can be triggered by running the
"mvpg" s390x kvm-unit-test with TCG. According to Richard: "... the
assert looks backward. We should only arrive there if nonfault was
true for the probe (otherwise the probe would have raised the
exception directly).  I would think we could just remove the assert."
