dsa: tag_mxl862xx: set dsa_default_offload_fwd_mark() 

The MxL862xx offloads bridge forwarding in hardware, so set
dsa_default_offload_fwd_mark() to avoid duplicate forwarding of
packets of (eg. flooded) frames arriving at the CPU port.

Link-local frames are directly trapped to the CPU port only, so don't
set dsa_default_offload_fwd_mark() on those.
