[PATCH] chelsio: transmit routine return values

The Chelsio driver does not return the correct values from
the transmit routine. It works because the values don't conflict,
but it is using the wrong defines. And -ENOMEM is not a legal return
value.

Since t1_sge_tx is only called in one place, making it static
allows compiler to be potentially inline it.
