Avi Kivity 16175a796d KVM: VMX: Don't allow uninhibited access to EFER on i386 
vmx_set_msr() does not allow i386 guests to touch EFER, but they can still
do so through the default: label in the switch.  If they set EFER_LME, they
can oops the host.

Fix by having EFER access through the normal channel (which will check for
EFER_LME) even on i386.
