[PATCH BlueZ 2/9 v3] audio: Fix handling of A2DP suspend indication

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

When accepting the suspend indication all callbacks should be notified
that suspend completed.

In addition to this fix not using avdtp_start return in indication
callback as well as in the confirmation.
