openpic: avoid buffer overrun on incoming migration
CVE-2013-4534
opp->nb_cpus is read from the wire and used to determine how many
IRQDest elements to read into opp->dst[]. If the value exceeds the
length of opp->dst[], MAX_CPU, opp->dst[] can be overrun with arbitrary
data from the wire.
Fix this by failing migration if the value read from the wire exceeds
MAX_CPU.
