KVM: selftests: access_tracking_perf_test: bump number of NUMA nodes to 32
It's rare to find a system that has more than 4 sockets,
but a system can have more than 4 NUMA nodes if each socket
exposes its chiplets as separate NUMA nodes.
In particular, our CI caught a failure in this test on a system with
two sockets, each containing an 'AMD EPYC 7601 32-Core Processor'.
Bump the limit to 32, just in case.
