stream_tag field is the last obstacle in removing skl_dsp_loader_ops
structure. It is required only during fw load procedure and never lives
outside of that process - prepare_fw functions take place directly
before actual FW file transfer and once that's done, these are
redundant. Update _prepare_fw routines to return stream_tag on success
and use said return immediately in _transfer_fw_host_dma.
