KVM: VMX: Modify the BUILD_BUG_ON_MSG of the 32-bit field in the vmcs_check16 function
According to the SDM, the meaning of field bit 0 is:
Access type (0 = full; 1 = high); must be full for 16-bit, 32-bit,
and natural-width fields. So there is no 32-bit high field here,
it should be a 32-bit field instead.
