ramips/mediatek: import a patch fixing bug in flow-offloading

From Frank Wunderlich <frank-w@public-files.de>:
Issue were traffic problems after a while with increased ping times if
flow offload is active.

It turns out that key_offset with cookie is needed in rhashtable_params
and head_offset was defined twice.
