fixup_controls() was modified in 25fb334 to return error code. One reference in the MediaTek MT8188 still returned void. Signed-off-by: John Cabaj <john.cabaj@canonical.com>

After a successful auxiliary_device_init(), aux_dev->dev.release (xe_nvm_release_dev()) is responsible for the kfree(nvm). When there is failure with auxiliary_device_add(), driver will call auxiliary_device_uninit(), which call put_device(). So that the .release callback will be triggered to free the memory associated with the auxiliary_device. Move the kfree(nvm) into the auxiliary_device_init() failure path and remove the err goto path to fix below error.

[ Upstream commit 8a44241 ] After a successful auxiliary_device_init(), aux_dev->dev.release (xe_nvm_release_dev()) is responsible for the kfree(nvm).

This is normally avoided because configs happen to not include CONFIG_MTK_IOMMU, but would be good to clean-up.
