memevents: Stop failure when attaching to an attached tracepoint The current implementation of libbpf bpf_detach_tracepoint API doesn't detach the program from the trace event[1]. This creates an issue when a MemEventListener deregisters and registers the same event type. Due to this we don't want to fail if the bpf program is already attached.
