KVM: nVMX: Drop STACK_FRAME_NON_STANDARD from nested_vmx_check_vmentry_hw()
...as it doesn't technically actually do anything non-standard with the
stack even though it modifies RSP in a weird way. E.g. RSP is loaded
with VMCS.HOST_RSP if the VM-Enter gets far enough to trigger VM-Exit,
but it's simply reloaded with the current value.
