Junhao He b660420f44 perf: hisi: Fix use-after-free when register pmu fails ...

[ Upstream commit b805cafc604bfdb671fae7347a57f51154afa735 ]

When we fail to register the uncore pmu, the pmu context may not been
allocated. The error handing will call cpuhp_state_remove_instance()
to call uncore pmu offline callback, which migrate the pmu context.
Since that's liable to lead to some kind of use-after-free.

Use cpuhp_state_remove_instance_nocalls() instead of
cpuhp_state_remove_instance() so that the notifiers don't execute after
the PMU device has been failed to register.
