nfc: st95hf: Make spi remove() callback return zero
If something goes wrong in the remove callback, returning an error code just results in an error message. The device still disappears. So don't skip disabling the regulator in st95hf_remove() if resetting the controller via spi fails. Also don't return an error code which just results in two error messages.
