perf/x86: Free hybrid state on PMU init failure
If PMU initialization fails, for example in check_hw_exists(), hybrid
state can be left partially initialized: x86_pmu.hybrid_pmu is not freed
and perf_is_hybrid remains set. This can leak memory and leave stale
hybrid state reachable after a failed init path.
Add x86_pmu_free_hybrid() and use it on PMU init failure paths so all
hybrid-related state is consistently reset.
