ASoC: wm_adsp: Don't use no_free_ptr() when passing to PTR_ERR()

It's no longer necessary to no_free_ptr() an auto-freed pointer before
passing it to PTR_ERR(). This was fixed by commit
cd7eb8f ("mm/slab: make __free(kfree) accept error pointers").

Removing the no_free_ptr() avoids the spurious warning
"inconsistent IS_ERR and PTR_ERR".
