KVM: nVMX: WARN once and fail VM-Enter if eVMCS sees VMFUNC[63:32] != 0
WARN and reject nested VM-Enter if KVM is using eVMCS and manages to
allow a non-zero value in the upper 32 bits of VM-function controls. The
eVMCS code assumes all inputs are 32-bit values and subtly drops the
upper bits. WARN instead of adding proper "support", it's unlikely the
upper bits will be defined/used in the next decade.
