x86, ioapic: Fix potential resume deadlock
Fix a potential deadlock when resuming; here the calling
function has disabled interrupts, so we cannot sleep.
Change the memory allocation flag from GFP_KERNEL to GFP_ATOMIC.
TODO: We can do away with this memory allocation during resume
by reusing the ioapic suspend/resume code that uses boot time
allocated buffers, but we want to keep this -stable patch
simple.
