transport: don't disconnect A2DP if canceling Acquire() with Release() User can cancel transport acquire by calling Release() while Acquire() is in progress. This calls a2dp_cancel() which sends AVDTP_ABORT_CMD, forcing AVDTP state transition to IDLE, and A2DP profile disconnects. However, Release()/Acquire() should only result to transitions between STREAMING/OPEN. The expected behavior is that either these calls return error, or they block until the target state is reached. Fix by: Release() during pending Acquire() first sends error reply to the Acquire. Then it waits for START to complete, then sends SUSPEND, and after that completes, then it replies. This also fixes SetConfiguration() after canceled Acquire(), which previously did not work due to AVDTP disconnect. Now it does START/SUSPEND -> CLOSE -> reconfigure.
