ASoC: Intel: sof_sdw: Only pass dai_link pointer around

Rather than passing around a pointer to the dai_link array and
an index into this array, simply pass a pointer to the current
dai_link. Also move the DAI link pointer sanity check to the end
of the DAI link creation, and change it to a warn on. This check
should only be hit if there is a serious bug in the machine driver,
so checking it on each iteration is excessive.
