ASoC: SOF: ipc4-control: Return on error in sof_ipc4_widget_kcontrol_…

…setup()

The patch adding the bytes control support moved the error check outside
of the list_for_each_entry() which was not correct as at the end of the
list_for_each_entry() the scontrol will no longer point where the error
happened, but it to the list head.

Restore the original logic and return on the first error with the error
code.
