Vitaly Kuznetsov 4e62aa96d6 KVM: x86: hyper-v: Check if guest is allowed to use XMM registers for hypercall input ...

TLFS states that "Availability of the XMM fast hypercall interface is
indicated via the “Hypervisor Feature Identification” CPUID Leaf
(0x40000003, see section 2.4.4) ... Any attempt to use this interface
when the hypervisor does not indicate availability will result in a #UD
fault."

Implement the check for 'strict' mode (KVM_CAP_HYPERV_ENFORCE_CPUID).
