Subject [PATCH] x86/ioapic: Disable interrupts when re-routing legacy IRQs

A sporadic hang with consequent crash is observed when booting Hyper-V Gen1
guests:

The issue is easily reproducible with a simple instrumentation: if
mdelay(10) is put between mp_setup_entry() and mp_register_handler() calls
in mp_irqdomain_alloc() Hyper-V guest always fails to boot when re-routing
IRQ0. The issue seems to be caused by the fact that we don't disable
interrupts while doing IOPIC programming for legacy IRQs and IRQ0 actually
happens. Decorate manipulations with legacy IRQs with local_irq_save()/
local_irq_restore().

It may make sense to have interrupts disabled for non-legacy IRQs as well
but I'm unaware of any bugs with them at this moment.
