[PATCH BlueZ] transport: Complete Acquire for Sink ASE entering Enabling

[PATCH BlueZ] transport: Complete Acquire for Sink ASE entering Enabling

[Simon Mikuda]

On the QoS to Enabling transition the IO is not yet available because
the CIS is not established, so the handler returns early and a pending
Acquire is left unanswered once the IO later arrives.

Notify the connecting callbacks once the fd is attached so the
transport can re-run the Enabling handling and complete the Acquire.
