KVM: nVMX: Introduce helpers to check if Hyper-V evmptr12 is valid/set
In order to get rid of raw 'vmx->nested.hv_evmcs_vmptr' accesses when
!CONFIG_KVM_HYPERV, introduce a pair of helpers:
nested_vmx_is_evmptr12_valid() to check that eVMPTR points to a valid
address.
nested_vmx_is_evmptr12_valid() to check that eVMPTR either points to a
valid address or is in 'pending' port-migration state (meaning it is
supposed to be valid but the exact address wasn't acquired from guest's
memory yet).
No functional change intended.
