Modified Files:
        src/sys/arch/x86/pci: pci_intr_machdep.c

Log Message:
In the NIOAPIC case, we do not need to support "legacy" irqs,
ie; We don't need to simultaneously pass back the irq in the
range 0 < irq < 16 (which are sometimes described as "legacy"
in src

This was non-obvious, until the semantics of "legacy" were
used in inconsistent ways in Xen (to also mean interrupts in
the 0 < irq < 256 range) which causes problems with attempting
to unify the sys/arch/x86/isa/isa_machdep.c:isa_intr_establish_xname()
function between XEN and !XEN

This commit should not affect current functionality on any
either native or Xen. It is needed for future code reorg, and
published now as a preview.
