mmc: owl: fix deferred probing

[ Upstream commit 3c482e1e830d79b9be8afb900a965135c01f7893 ]

The driver overrides the error codes returned by platform_get_irq() to
-EINVAL, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the
error codes upstream.
