[PATCH] i386/x86_64: Remove global IO_APIC_VECTOR

Which vector an irq is assigned to now varies dynamically and is
not needed outside of io_apic.c.  So remove the possibility
of accessing the information outside of io_apic.c and remove
the silly macro that makes looking for users of irq_vector
difficult.

The fact this compiles ensures there aren't any more pieces
of the old CONFIG_PCI_MSI weirdness that I failed to remove.
