[PATCH v6 88/90] KVM: x86: Remove BUILD_BUG_ON() x86_capability[] check

[Ahmed S. Darwish]

KVM's direct access to cpuinfo_x86::x86_capability[] has been replaced with
the cpuid_word_*() APIs.  The former is getting removed from the kernel.

Adjust the kvm_cpu_caps[] alignment comment accordingly.

Remove BUILD_BUG_ON() related to x86_capability[] as it does not matte
anymore.
