Subject: [PATCH net-next 07/13] mlxsw: spectrum_matchall: Pass mall_entry as arg to mlxsw_sp_mall_port_sample_add()

From: Jiri Pirko <jiri@...lanox.com>

In the preparation for future changes, have the
mlxsw_sp_mall_port_sample_add() function to accept mall_entry including
all needed info originally obtained from cls and act pointers.
