powerpc/perf/hv-24x7: Fail 24x7 initcall if create_events_from_catalog() fails
As Michael pointed out, create_events_from_catalog() fails when we
either have:
- a kernel bug
- some sort of hypervisor misconfiguration
- ENOMEM
In all the above cases, we can also fail 24x7 initcall.
For hypervisor errors, EIO is used so there is something reported
in dmesg.
