KVM: s390: Fix external interrupt interception
The external interrupt interception can only occur in rare cases, e.g. when the PSW of the interrupt handler has a bad value. The old handler for this interception simply ignored these events (except for increasing the exit_external_interrupt counter), but for proper operation we either have to inject the interrupts manually or we should drop to userspace in case of errors.
