KVM: simplify kvm_cpu_exec hook

We don't need to use cpu_loop_exit() because we never use the

Fix interrupt exclusion via SSTEP_NOIRQ

Commit #5620 revealed an issue of the SSTEP_NOIRQ masking that was
applied on all interrupt sources (including internal ones) when single

infinite loop when CPU_INTERRUPT_EXIT was pending on SSTEP resume. That...
