ALSA: firewire-tascam: deleyed registration of sound card
When some tascam units are connected sequentially, userspace
applications are involved at bus-reset state on IEEE 1394 bus. In the
state, any communications can be canceled. Therefore, sound card
registration should be delayed till the bus gets calm.
This commit achieves it.
