[PATCH] mfd: sec-core: add missing sec_irq_init() return value checking

[Bartlomiej Zolnierkiewicz]

sec_irq_init() can fail if it encounters unknown device type or
on regmap_add_irq_chip() error.  Add missing sec_irq_init() return
value checking to sec_pmic_probe().

Tested on Insignal's Exynos4412 based Origen board.
