KVM: arm64: Have kvm_psci_vcpu_on() use WRITE_ONCE() to update mp_state
All accessors of kvm_vcpu_arch::mp_state should be {READ,WRITE}_ONCE(),
since readers of the mp_state don't acquire the mp_state_lock.
Nonetheless, kvm_psci_vcpu_on() updates the mp_state without using
WRITE_ONCE(). So, fix the code to update the mp_state using WRITE_ONCE.
