KVM: x86: remove always-false condition in kvmclock_sync_fn
The 'kvmclock_periodic_sync' is a readonly param that cannot change after
bootup.
The kvm_arch_vcpu_postcreate() is not going to schedule the
kvmclock_sync_work if kvmclock_periodic_sync == false.
As a result, the "if (!kvmclock_periodic_sync)" can never be true if the
kvmclock_sync_work = kvmclock_sync_fn() is scheduled.
