mctpd: reset pool for invalid set endpoint id response

If endpoint responds with some error in
endpoint_send_set_endpoint_id() , assumed bridge pool space
needs to reset too, this is needed as it misleads remove_peer()
to delete gateway routes too which will only be created
after bridge pool allocation
