This commit fix out of specification about the value of FDF field in out packet
with 'no data'. This affects blocking mode.
According to IEC 61883-6, there is two way to generate AMDTP packets include no
data in blocking mode.
Way 1. an empty packet defined in IEC 61883-1
- Size of packet is 2 quadlets.
- The value of FDF is sfc.
- The packet includes only CIP headers
Way 2. a special non-empty packet defined in IEC 61883-6
- Size of packet is following to blocking mode
- The value of FDF is 0xff. This value is 'NO-DATA'. This means 'The receiver'
must ignore all the data in a CIP with this FDF code'.
- The packet includes dummy data.
But current implementation is a combination of them.
- Size of packet is 2 (way 1)
- FDF = 0xff (way 2)
This causes BeBoB chipset cannot sound.
This patch applies Way 1.

When aborting a PCM stream, the xrun is signaled only if the stream is
running. When disconnecting a PCM stream, calling snd_card_disconnect()
too early would change the stream into a non-running state and thus
prevent the xrun from being noticed by user space.
To prevent this, move the snd_card_disconnect() call after the xrun.

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.
