kernel: perf/core: Detach event groups during remove_on_exec

A flaw was found in the Linux kernel's performance monitoring unit PMU subsystem. This vulnerability occurs when a performance event group leader is removed during process execution, but its associated events siblings remain active and linked to a stale list. This inconsistent state can lead to a...
