[PATCH] ASoC: nau8821: Don't unconditionally free interrupt

[Mark Brown <broonie@kernel.org>]

The remove() operation unconditionally frees the interrupt for the device
but we may not actually have an interrupt so there might be nothing to
free. Since the interrupt is requested after all other resources we don't
need the explicit free anyway, unwinding is guaranteed to be safe, so just
delete the remove() function and let devm take care of things.
