This driver allocates a dynamic cpu hotplug state but never releases it.
If reloaded in a loop it will quickly trigger a WARN message:
"No more dynamic states available for CPU hotplug"
Fix by calling cpuhp_remove_multi_state on remove like several other
perf pmu drivers.
Also fix the cleanup logic on probe error paths: add the missing
cpuhp_remove_multi_state call and properly check the return value from
cpuhp_state_add_instant_nocalls.
Fixes:
