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);

Currently the driver assumes that queue IDs start at 0 but that's true
only for function 0.  To support operation on other functions get the
start of the queue ranges from FW and offset accordingly.

Add support for running the driver on any PCI function.  Mostly this
entails replacing a constant 0 in a number of calls with the variable
function number.

Commit 1704d748 ("cxgb4vf: small changes
to message processing structures/macros") was incomplete and causes cxgb4
to write bad TSO descriptors.  Fix that up by reverting the offending part
of that commit and adjusting field accesses now that they are one level
deeper.
