Bluetooth: GATT: Fix not updating previous node

Browse source 
When iterating to the subscriptions to be removed the code has to keep
a reference to the previous node but it case the subscription matches but
doesn't need to be removed it doesn't update the prev node which may
corrupt the list in case the next node end up being removed.
