Follow up to the recent hdac_stream-related series of mine [1].
Addresses three topics:

- false-positive timeout (-110) messages that appear during firmware
  loading procedure
- null-ptr-deref when assigning stub substream of COUPLED type. 'Stub'
  as precisely those kind of substreams are utilized for code-loading
  procedure
- hstream->fifo_size initialization, superfluous '+1'

The two fixes lead the way, there is no dependency of patch 3/3 on
either of them.
