[PATCH] ASoC: SOF: ipc4-topology: Free the ida when IPC fails in sof_ipc4_widget_setup()

[Peter Ujfalusi]

The allocated ida needs to be freed up if the IPC message fails since
next time when we try again to set up the widget we are going to try to
allocate another ID and given enough tries, we are going to run out of
unique IDs.

Fixes: 711d0427c713 ("ASoC: SOF: ipc4-topology: move ida allocate/free to widget_setup/free")
