KVM: VMX: Drop guest CPUID check for VMXE in vmx_set_cr4()
Drop vmx_set_cr4()'s somewhat hidden guest_cpuid_has() check on VMXE now
that common x86 handles the check by incorporating VMXE into the CR4
reserved bits, i.e. in cr4_guest_rsvd_bits. This fixes a bug where KVM
incorrectly rejects KVM_SET_SREGS with CR4.VMXE=1 if it's executed
before KVM_SET_CPUID{,2}.
Fixes: 5e1746d6205d ("KVM: nVMX: Allow setting the VMXE bit in CR4")
