hvm: Improve APIC INIT/SIPI emulation, fixing it for call paths other than x86_emulate().
In particular, on broadcast/multicast INIT/SIPI, we handle all target
APICs at once in a single invocation of the init/sipi tasklet. This
avoids needing to return an X86EMUL_RETRY error code to the caller,
which was being ignored by all except x86_emulate().
The original bug, and the general approach in this fix, pointed out by
Intel (yang.z.zhang@intel.com).
