Subject: [PATCH AUTOSEL 4.19 032/123] ASoC: qcom: Set dai_link id to each dai_link

From: Rohit kumar <rohitkr@...eaurora.org>

[ Upstream commit 67fd1437d11620de8768b22fe20942e752ed52e9 ]

Frontend dai_link id is used for closing ADM sessions.
During concurrent usecase when one session is closed,
it closes other ADM session associated with other usecase
too. Dai_link->id should always point to Frontend dai id.
Set cpu_dai id as dai_link id to fix the issue.
