[POWERPC] Depend on ->initialized in calc_steal_time
If CPU_FTR_PURR is not set, we will never set cpu_purr_data->initialized.
Checking via __get_cpu_var on 64 bit avoids one dependent load compared
to cpu_has_feature in the not-present case, and is always required when
it is present. The code is under CONFIG_VIRT_CPU_ACCOUNTING so 32 bit
will not be affected.
