w1: omap-hdq: fix error return code in omap_hdq_probe()
platform_get_irq() returns an error code, but the omap_hdq
driver ignores it and always returns -ENXIO. This is not correct,
and prevents -EPROBE_DEFER from being propagated properly.
Notice that platform_get_irq() no longer returns 0 on error.
Print error message and propagate the return value of
platform_get_irq on failure.
