s390x: protvirt: Fix stray error_report_err in s390_machine_protect

In case the protection of the machine fails at s390_pv_vm_enable(),
we'll currently report the local_error variable. Problem is that
there's no migration blocker error that we can report at this point so
the pointer is always NULL which leads to a SEGFAULT.

Let's remove the error report.
