Will Deacon c385cda0e7 drivers/perf: arm_pmu: Fix failure path in PM notifier ...

commit 0d7fd70f26 upstream.

Handling of the CPU_PM_ENTER_FAILED transition in the Arm PMU PM
notifier code incorrectly skips restoration of the counters. Fix the
logic so that CPU_PM_ENTER_FAILED follows the same path as CPU_PM_EXIT.
