The "snd_pcm_hw_constraint_minmax" call may return a positive
non-error integer so that the subsequent "snd_pcm_hw_constraint_mask64"
call is never invoked, thus the formats are never enforced.
Fix the error handling so that only negative results are considered.

AMIX SAIs frequency was doubled in order to
support the [98k rate X 8 channels X 32 bit width].
As consequence the criteria to enforce the rates
constrainsts needs to be changed accordingly.

The intention of currently implemented primary SAI power-on/off
on BE startup/shutdown was to make sure the primary SAI is
powered-on when the playback is started on the secondary SAI.
However in a such scenario the primary SAI is powered-on when
the primary SAI output is recorded.
