Pre-existing: max310x_remove() has cancelled the works before
unregistering the ports, and the probe error path has lacked the
cancels, since the works were introduced - this patch only moves the
ISR's direct handle_tx() call into the existing tx_work. The series'
teardown interlock narrows the window; reordering remove() and adding
the probe error path cancels is planned as a follow-up series, since
it is unrelated to the RS485 work here.
