soundwire: bus: add dev_warn() messages to track UNATTACHED devices
In rare cases, some devices seem to lose sync and never re-attach on
the bus. This seems to happen only when there are more than one device
per link, which suggests either an electrical issue, a race condition
or a state machine issue.
Add two dev_warn() messages to identify the sequence by which the
devices become UNATTACHED.
