mfd: wm831x-auxadc: Prevent use after free in wm831x_auxadc_read_irq()
The "req" struct is always added to the "wm831x->auxadc_pending" list, but it's only removed from the list on the success path. If a failure occurs then the "req" struct is freed but it's still on the list, leading to a use after free.
