Bluetooth: Audio: Add missing error checks for calls to bt_gatt_subscribe

Browse source 
Several places the LE Audio clients called bt_gatt_subscribe without
checking the return value, which could cause some issues in the worst
case, and in the best case, cause some unexpected behavior.

Some implementations had a bit more updating to handle the new
behavior.
