EDAC/altera: Fix deferred probing

Browse Source 
commit 279eb8575fdaa92c314a54c0d583c65e26229107 upstream.

The driver overrides the error codes returned by platform_get_irq() to
-ENODEV for some strange reason, so if it returns -EPROBE_DEFER, the
driver will fail the probe permanently instead of the deferred probing.
Switch to propagating the proper error codes to platform driver code
upwards.
