irqchip/stm32-exti: Fix irq_mask/irq_unmask for direct events

The driver has to mask/unmask the corresponding flag in the
Interrupt Mask Register (IMR).
This is already done for configurable event, while direct events
only forward the mask/unmask request to the parent.

Use the existing stm32_exti_h_mask()/stm32_exti_h_unmask() for
direct events too.
