Benjamin Herrenschmidt e0d82a0a4e perf_counter/powerpc: Check oprofile_cpu_type for NULL before using it ...

If the current CPU doesn't support performance counters,
cur_cpu_spec->oprofile_cpu_type can be NULL. The current
perf_counter modules don't test for that case and would thus
crash at boot time.

Bug reported by David Woodhouse.
