net: Make gro complete function to return void
tcp_gro_complete() function only updates the skb fields related to GRO
and it always returns zero. All the 3 drivers which are using it
do not check for the return value either.
Change it to return void instead which simplifies its callers as
error handing becomes unnecessary.
