Add a flag to snd_fw_transaction() to allow it to abort when a bus reset
happens. This removes most of the duplicated error handling loops that
were required around calls to the low-level fw_run_transaction().
Also add a flag to suppress error messages; errors are expected when we
attempt to clean up after the device was unplugged.

Make struct ieee1394_device_id.driver_data actually avaliable to
1394 protocol drivers. This is especially useful to 1394 audio drivers
for model-specific parameters and methods.

Fix to return -ENOMEM in the kmalloc() error handling
case instead of 0, as done elsewhere in this function.

FireWire upper layer drivers are converted from generic
struct driver.probe() and .remove()
to bus-specific
struct fw_driver.probe() and .remove().
The new .probe() adds a const struct ieee1394_device_id *id argument,
indicating the entry in the driver's device identifiers table which
matched the fw_unit to be probed. This new argument is used by the
snd-firewire-speakers driver to look up device-specific parameters and
methods. There is at least one other FireWire audio driver currently in
development in which this will be useful too.
The new .remove() drops the unused error return code.
Although all in-tree drivers are being converted to the new methods,
support for the old methods is left in place in this commit. This
allows public developer trees to merge this commit and then move to the
new fw_driver methods.
