drm/amdkfd: Avoid null pointer in SMI event 



Power Management IP is initialized/enabled before KFD init. When a
thermal throttling happens before kfd_smi_init is done, calling the KFD
SMI update function causes a stack dump by referring a NULL pointer (
smi_clients list). Check if kfd_init is completed before calling the
function.
