[PATCH BlueZ] gatt: Fix Acquire* reply handling

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

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

Originally these operation did not set any owner_queue which caused
them to crash if the attribute is freed before the respose, to fix that
the reply will now check if owner_queue was reset to NULL which means
the attribute is no longer available but the owner_queue was never set
in the first place so this ensures they are now setup properly.
