x86: DT: Fix return condition in irq_create_of_mapping()



The xlate() function returns 0 or a negative error code. Returning the
error code blindly will be seen as an huge irq number by the calling
function because irq_create_of_mapping() returns an unsigned value.

Return 0 (NO_IRQ) as required.
