[ Upstream commit 85a7555575a0e48f9b73db310d0d762a08a46d63 ]
The error handling frees "ctl" but it's still on the "dsp->ctl_list"
list so that could result in a use after free. Remove it from the list
before returning.
Fixes: 2323736dca72 ("ASoC: wm_adsp: Add basic support for rev 1 firmware file
format")
