[PATCH v2 2/2] i2c: synquacer: fix deferred probing

[Sergey Shtylyov <s.shtylyov@omp.ru>]

The driver overrides the error codes returned by platform_get_irq() to
-ENODEV, 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...
