[PATCH 17/28] android/scpp: Remove tracking pending gatt operations

[Mariusz Skamra <mariusz.skamra@xxxxxxxxx>]

From: Mariusz Skamra <mariusz.skamra@xxxxxxxxx>

Since the use of bt_gatt_client there is no need to queue pending gatt
operations. bt_gatt_client already keeps track on that, so that
on bt_gatt_client_unref the queue of pending requests is destroyed.
