[PATCH 2/2] ASoC: amd: closing specific instance.

[Ravulapati Vishnu vardhan rao]

The steps to reproduce:

Record from the internal mic :
(arecord -D hw:1,2 -f dat /dev/null -V stereos)

Record from the headphone mic:
(arecord -D hw:1,0 -f dat /dev/null -V stereos)

Kill the recording from internal mic.
We can see the recording from the headphone mic is broken.

This patch rectifies the issue reported.
