Bluetooth: GATT: Fix BT_GATT_AUTO_DISCOVER_CCC

Browse source 
When using BT_GATT_AUTO_DISCOVER_CCC if the ccc_handle is not set
bt_gatt_subscribe would initiate a discovery to locate the CCC handle
but instead of awaiting it to complete the code does proceed to call
gatt_write_ccc even with ccc_handle being 0x0000 which is invalid.
