KVM: SVM: Handle multiple logical targets in AVIC kick fastpath

Browse source

Iterate over all target logical IDs in the AVIC kick fastpath instead of
bailing if there is more than one target.  Now that KVM inhibits AVIC if
vCPUs aren't mapped 1:1 with logical IDs, each bit in the destination is
guaranteed to match to at most one vCPU, i.e. iterating over the bitmap
is guaranteed to kick each valid target exactly once.
