xen, cpu_hotplug: Prevent an out of bounds access
[ Upstream commit 201676095dda7e5b31a5e1d116d10fc22985075e ]
The "cpu" variable comes from the sscanf() so Smatch marks it as
untrusted data. We can't pass a higher value than "nr_cpu_ids" to
cpu_possible() or it results in an out of bounds access.
Fixes: d68d82afd4c8 ("xen: implement CPU hotplugging")
