hal: Return proper value from get_controller_stream_from_params.

When stream and controller params are available, check if their
values are proper or not, if values are proper, return 0 from
this API, if values are not proper, return -EINVALID. If the values
are not present in the string, in that case, return 0. This is to
avoid returning of -22 error even if the values are not present which
leads to failure of VTS testcases.
