irqdomain: Mask irq type in irq_domain_xlate_onetwocell()

According to the xlate() callback definition, the 'out_type' parameter
needs to be the "linux irq type".

A mask for such bits exists, IRQ_TYPE_SENSE_MASK, which is correctly
applied in irq_domain_xlate_twocell()

So use it for irq_domain_xlate_onetwocell() as well.
