mtd: nand: mtk: fix error return code in mtk_ecc_probe()

platform_get_irq() returns an error code, but the mtk_ecc driver
ignores it and always returns -EINVAL. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.

Print and propagate the return value of platform_get_irq on failure.

This issue was detected with the help of Coccinelle.
