[PATCH v2 net-next 3/3] gro: give 'hash' variable in dev_gro_receive() a less confusing name

[Alexander Lobakin]

'hash' stores not the flow hash, but the index of the GRO bucket
corresponding to it.
Change its name to 'bucket' to avoid confusion while reading lines
like '__set_bit(hash, &napi->gro_bitmask)'.
