mlxsw: spectrum_qdisc: Add mlxsw_sp_qdisc_get_class_stats()
Add a wrapper around mlxsw_sp_qdisc_collect_tc_stats() and
mlxsw_sp_qdisc_update_stats() for the simple case of doing both in one go:
mlxsw_sp_qdisc_get_class_stats(). Dispatch to that function from
mlxsw_sp_qdisc_get_red_stats(). This new function will be useful for other
leaf Qdiscs as well.
