[Qemu-trivial] [PULL 11/23] hw/intc/apic.c: Use uint32_t for mask word in foreach_apic

[Michael Tokarev]

From: Peter Maydell <address@hidden>

Use unsigned arithmetic for operations on the mask word
in the foreach_apic() macro, to avoid relying on undefined
behaviour when shifting into the sign bit.
