ide: Fix irq flags madness 

commit ec1a123 (IDE: pass IRQ flags to the IDE core) introduced the
bogosity of passing unfiltered resource->flags to the irq_flags which
are used for request_irq. It results in random bits set (especially
IORESOURCE_IRQ which maps to IRQF_PER_CPU).

Filter the bits proper.
