perf_events: Fix invalid pointer when pid is invalid
This patch fixes an error in perf_event_open() when the pid provided by the user is invalid. find_lively_task_by_vpid() does not return NULL on error but an error code. Without the fix the error code was silently passed to find_get_context() which would eventually cause a invalid pointer dereference.
