ALSA: bebob: expand sleep just after breaking connections for protocol version 1
As long as I investigated, some devices with BeBoB protocol version 1
can be freezed during several hundreds milliseconds after breaking
connections. When accessing during the freezed time, any transaction
is corrupted. In the worst case, the device is going to reboot.
I can see this issue in:
* Roland FA-66
* M-Audio FireWire Solo
This commit expands sleep just after breaking connections to avoid
the freezed time as much as possible. I note that the freeze/reboot
behaviour is similar to below models:
* Focusrite Saffire Pro 10 I/O
* Focusrite Saffire Pro 26 I/O
The above models certainly reboot after breaking connections.
