x86: fix IRQ migration when using directed EOI (broken with c/s 20465)
In directed-EOI mode, there is no chance to do the migration in
mask_and_ack_level_ioapic_irq(), as the remote IRR bit can''t
possibly
be clear after issuing the EOI to the LAPIC. Consequently,
there''s no
point to even try. Instead, migration must be done in
end_level_ioapic_irq(), and it requires masking the interrupt source
prior to issuing the EOI to the IO-APIC.

I think this is the same wrong answer as before, probably. Sorry.
But there is a real build failure for 32-bit Xen - see my other mail.
Ian.
