Sean Christopherson cb61de2f48 KVM: nVMX: do not skip VMEnter instruction that succeeds
A successful VMEnter is essentially a fancy indirect branch that
pulls the target RIP from the VMCS.  Skipping the instruction is
unnecessary (RIP will get overwritten by the VMExit handler) and
is problematic because it can incorrectly suppress a #DB due to
EFLAGS.TF when a VMFail is detected by hardware (happens after we
skip the instruction).

Now that vmx_nested_run() is not prematurely skipping the instr,
use the full kvm_skip_emulated_instruction() in the VMFail path
of nested_vmx_vmexit().  We also need to explicitly update the
GUEST_INTERRUPTIBILITY_INFO when loading vmcs12 host state.
