Fix for IDE controller. Some weird controllers generate an interrupt even if IDE interrupts are disabled and no IDE devices. For example, notebook ASUS K72F - IDE controller 010185 generates false interrupt when we work with the IDE controller 01018f. For this reason, the interrupt handler does not need to be installed if both channel IDE controller running in PIO mode.
