x86/IRQ: eliminate irq_vector[]
The vector is already being tracked in struct irq_desc's arch.vector
member, so there's no real need for a second place where this to get
stored. The only caveat is that legacy vectors (used for interrupts
handled through the 8259) must be special cased to not prevent non-
legacy vectors from being assigned.
