target-i386: wake up processors that receive an SMI

Browse source 
An SMI should definitely wake up a processor in halted state!
This lets OVMF boot with SMM on multiprocessor systems, although
it halts very soon after that with a "CpuIndex != BspIndex"
assertion failure.

Backports commit a9bad65d2c1f61af74ce2ff43238d4b20bf81c3a from qemu
