p54: remove free_on_tx parameter
This patch simplifies the tx code a bit and will be necessary for
the upcoming stlc45xx<->p54 port.
In detail: we no longer have to tell all back-end drivers directly,
if we want to free a frame right after it was send to the firmware,
or if we do it in the library callback later.
