Dan Carpenter 201676095d xen, cpu_hotplug: Prevent an out of bounds access
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: d68d82afd4 ("xen: implement CPU hotplugging")
