ALSA: oxfw: delayed registration of sound card

Browse source

Some oxfw based units tends to fail asynchronous communication when
IEEE 1394 bus is under bus-reset state. When registering sound card
instance at unit probe callback, userspace applications can be involved
to the state.

This commit postpones the registration till the bus is calm.
