So the AMD NB stuff in events/amd/core.c is only for Fam10, Fam15 got
its own uncore driver. (Fam10 had the uncore events through the same
counters as the core PMU with with 'fun' constraints).

And since Fam10 isn't affected by this change in x86_max_cores, this
_should_ work out, IF that NB code knows to switch off properly when not
required.
