drivers/net: avoid some skb->ip_summed initializations
fresh skbs have ip_summed set to CHECKSUM_NONE (0)
We can avoid setting again skb->ip_summed to CHECKSUM_NONE in drivers.
Introduce skb_checksum_none_assert() helper so that we keep this
assertion documented in driver sources.
Change most occurrences of :
skb->ip_summed = CHECKSUM_NONE;
by :
skb_checksum_none_assert(skb);
