ipc4: helper: fix stream params frame format update

When making assignment from ipc4_base_module_cfg, received in
Init Instance IPC to sof_ipc_stream_params, valid_bit_depth is used
to set frame_fmt instead of container size. It is then applied to
buffer format in params/prepare stage. Thus, leads to inconsistancy
between buffer format and actual audio stream.
