Zero-length arrays are deprecated[1] and we are moving towards adopting C99 flexible-array members instead. So, replace zero-length array declaration in struct mlx5e_flow_meter_aso_obj with flex-array member. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [2].
