net: mscc: ocelot: add a new ocelot_vcap_block_find_filter_by_id function
And rename the existing find to ocelot_vcap_block_find_filter_by_index. The index is the position in the TCAM, and the id is the flow cookie given by tc. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
