Fix creation of DirectIO overwriting fifo config

Browse Source 
Creating a direct IO should not overwrite the fifo
configuration. The fifo configuration can be updated
before creating the direct io if needed.
This fixes an expected change in behavior for clients
who were calling NewDirectIO previously with terminal
configured on the fifo.
