Bluetooth: host: Fix Suggested Default Data Len for QUIRK_NO_AUTO_DLE

Browse source 
Add back call to LE Write Suggested Default Data Length
command so that new connections, receiving Data Length
Update procedure before local device can auto initiate, can
respond with the suggested default data length Tx octets
and Tx time.
