KVM: selftests: Verify single-stepping a fastpath VM-Exit exits to us…
…erspace In x86's debug_regs test, change the RDMSR(MISC_ENABLES) in the single-step testcase to a WRMSR(TSC_DEADLINE) in order to verify that KVM honors KVM_GUESTDBG_SINGLESTEP when handling a fastpath VM-Exit. Note, the extra coverage is effectively Intel-only, as KVM only handles TSC_DEADLINE in the fastpath when the timer is emulated via the hypervisor timer, a.k.a. the VMX preemption timer.
