mlxsw: spectrum_span: On policer_id_base_ref_count, use dec_and_test
When unsetting policer base, the SPAN code currently uses refcount_dec(). However that function splats when the counter reaches zero, because reaching zero without actually testing is in general indicative of a missing cleanup. There is no cleanup to be done here, but nonetheless, use refcount_dec_and_test() as required. Signed-off-by:Petr Machata <petrm@mellanox.com> Reviewed-by:
