net/sfc: do not push fast free offload to default TxQ config

[ upstream commit f67615e ]

Doing so is wrong since fast free is an adapter-wide offload.

Technically, the offending commit (see "Fixes" tag) does not
induce failures, however, such started to occur after commit
a4996bd ("ethdev: new Rx/Tx offloads API") had shown up,
because of the strict offload validation in the generic code.

Fixes: c78d280 ("net/sfc: convert to new Tx offload API")
