Fix bind_irq_vector() destination

The "mask" covered all online cpus in the "domain". It should be used
as destination later, instead of using "domain" directly.

Fix serial interrupt's destination

Lowest Priority can't use with invalid cpu_mask, and the default value
of CPU_MASK_ALL may cover CPU which wasn't online.
