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). Signed-off-by: Keir Fraser <keir@xen.org>
