[PATCH] libxl/CPUID: drop two more feature flag table entries

[Jan Beulich <jbeulich@xxxxxxxx>]

Two entries were left in place by d638fe233cb3 ("libxl: use the cpuid
feature names from cpufeatureset.h"), despite matching the generated
names.

Permitting "psn", "ia64, "cntxid", and "perfctr_*" when the hypervisor
doesn't even know of the bits (perhaps wrongly so) is kind of odd as
well. Permitting bits like "est", which the hypervisor knows of but
doesn't expose to guests, is also questionable.

I wouldn't really call this a bug fix (the entries are simply redundant,
but nothing bad would happen with them there), hence no Fixes: tag.
