KVM: x86: move nested-related kvm_x86_ops to a separate struct
Clean up some of the patching of kvm_x86_ops, by moving kvm_x86_ops related to
nested virtualization into a separate struct.
As a result, these ops will always be non-NULL on VMX. This is not a problem:
* check_nested_events is only called if is_guest_mode(vcpu) returns true
* get_nested_state treats VMXOFF state the same as nested being disabled
* set_nested_state fails if you attempt to set nested state while
nesting is disabled
* nested_enable_evmcs could already be called on a CPU without VMX enabled
in CPUID.
* nested_get_evmcs_version was fixed in the previous patch
