For oFono-backed HFP the stream sample rate is only known whe the
transport changes its state to playing, as a paramenter of
NewConnection(). On this moment if the stream sample rate is different
from the sink/source one, the sink-inputs/source-outputs are stashed,
the sink and source are destroyed and re-created with the new rate, and
the sink-inputs/source-outputs restored.
