staging: switch to netif_napi_add_weight()

staging: switch to netif_napi_add_weight()

netif_napi_add() will soon default to weight of 64 instead of
requiring the user to specify that parameter. Most users already
pass or should pass 64. Move the callers in staging to
netif_napi_add_weight() which will keep the argument.
This way we'll avoid a huge cross-tree conversion when
argument is removed.
