mlxsw: spectrum: Allow fetch-and-clear of flow counters
For the report_delta-like interface like a previous patch has added for
collection of NH group statistics, it's easiest to read the counter and
have the HW clear it right away. Thus, change mlxsw_sp_flow_counter_get()
to take a bool indicating whether this should be done.
