Sean Christopherson 02343cf207 KVM: vmx: do not unconditionally clear EFER switching
Do not unconditionally call clear_atomic_switch_msr() when updating
EFER.  This adds up to four unnecessary VMWrites in the case where
guest_efer != host_efer, e.g. if the load_on_{entry,exit} bits were
already set.
