mfd: Apply irq_mask_cur before handling max77686 interrupts 

According to TRM, though we mask the interrupts in interrupt-mask register,
interrupt source-register still provide the status of the masked interrupts.
So we should apply irq_mask_cur to read interrupt source-register value before
handling.
