ASoC: q6apm-lpass-dai: close graph on prepare errors
[ Upstream commit be1fae62cf253a5b67526cee9fbc07689b97c125 ]
There is an issue around with error handling and graph management with
the exising code, none of the error paths close the graph, which result in
leaving the loaded graph in dsp, however the driver thinks otherwise.
This can have a nasty side effect specially when we try to load the same
graph to dsp, dsp returns error which leaves the board with no sound and
requires restart.
Fix this by properly closing the graph when we hit errors between
open and close.
