irqchip/stm32-exti: Remove check on always false condition
The field drv_data is assigned during driver's probe, where it's
already checked to be not NULL.
Remove the always false check '!host_data->drv_data'.
This fixes a warning "variable dereferenced before check" detected
by '0-DAY CI Kernel Test Service'.
Fixes: c297493336b7 ("irqchip/stm32-exti: Simplify irq description table")
