[kvm-unit-tests Patch 3/5] x86: pmu: Enlarge cnt array length to 64 in check_counters_many()

[Dapeng Mi]

Considering there are already 8 GP counters and 4 fixed counters on
latest Intel CPUs, like Sapphire Rapids. The original cnt array length
10 is definitely not enough to cover all supported PMU counters on these
new CPUs and it would cause PMU counter validation failures.

It's probably more and more GP and fixed counters are introduced in the
future and then directly extends the cnt array length to 64.
