kvm: Check KVM_CAP_MAX_VCPUS at vm level
KVM with TDX support starts to report different KVM_CAP_MAX_VCPUS per
different VM types. So switch to check the KVM_CAP_MAX_VCPUS at vm level.
KVM still returns the global KVM_CAP_MAX_VCPUS when the KVM is old that
doesn't report different value at vm level.
