staging/fwserial: don't use PREPARE_WORK
PREPARE_[DELAYED_]WORK() are being phased out. They have few users
and a nasty surprise in terms of reentrancy guarantee as workqueue
considers work items to be different if they don't have the same work
function.
fwtty_peer->work is multiplexed with multiple work functions.
Introduce fwserial_peer_workfn() which invokes fwtty_peer->workfn and
always use it as the work function and update the users to set the
->workfn field instead of overriding the work function using
PREPARE_WORK().
It would probably be best to route this with other related updates
through the workqueue tree.
Compile tested.
