Suresh Siddha 05c3dc2c4b x86, ioapic: Fix non atomic allocation with interrupts disabled 
Impact: fix possible race

save_mask_IO_APIC_setup() was using non atomic memory allocation while getting
called with interrupts disabled. Fix this by splitting this into two different
function. Allocation part save_IO_APIC_setup() now happens before
disabling interrupts.
