x86: Increase the default NR_CPUS to 256
Changeset 21012:ef845a385014 bumped the default to 128 about one and a
half years ago. Increase it now to 256, as systems with eg. 160
logical CPUs are becoming (have become) common.

My bisector is pretty reliable nowadays. Looking at the revision
graph it tested before/after/before/after/before/after, ie three times
each on the same host.
This change looks innocuous enough TBH. Is there any way this change
could have broken a PV-on-HVM guest ? Note that RHEL6, which is what
this is testing, seems to generally be full of bugs.
If the problem is indeed a bug in the current RHEL6 then I will add
this test to the "do not care" list.
In what way was the guest broken? How many physical cores/threads was
the hypervisor running on?
Thanks,
lacos
