[PATCH BlueZ] audio/A2DP: Return -ENOPROTOOPT if record doesn't exist

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

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

In case record is not registered it means no endpoint is available so
return -ENOPROTOOPT to indicate that it is currently not available.
