x86, kvm: Call restore_sched_clock_state() only after %gs is initialized
s2ram broke due to this KVM commit:
b74f05d61b73 x86: kvmclock: abstract save/restore sched_clock_state
restore_sched_clock_state() methods use percpu data, therefore
they must run after %gs is initialized, but before mtrr_bp_restore()
(due to lockstat using sched_clock).
Move it to the correct place.
