i2c: iop3xx: fix deferred probing
When adding the code to handle platform_get_irq*() errors in the commit
489447380a29 ("handle errors returned by platform_get_irq*()"), the
actual error code was enforced to be -ENXIO in the driver for some
strange reason. This didn't matter much until the deferred probing was
introduced -- which requires an actual error code to be propagated
upstream from the failure site.
While fixing this, also stop overriding the errors from request_irq() to
-EIO (done since the pre-git era).
Fixes: 489447380a29 ("[PATCH] handle errors returned by platform_get_irq*()")
