KVM: s390: interrupt: Fix single-stepping into interrupt handlers
After single-stepping an instruction that generates an interrupt, GDB
ends up on the second instruction of the respective interrupt handler.
The reason is that vcpu_pre_run() manually delivers the interrupt, and
then __vcpu_run() runs the first handler instruction using the
CPUSTAT_P flag. This causes a KVM_SINGLESTEP exit on the second handler
instruction.
Fix by delaying the KVM_SINGLESTEP exit until after the manual
interrupt delivery.
