[PATCH v2 42/49] KVM: x86: Drop unnecessary check that cpuid_entry2_find() returns right leaf

[Sean Christopherson]

Drop an unnecessary check that kvm_find_cpuid_entry_index(), i.e.
cpuid_entry2_find(), returns the correct leaf when getting CPUID.0x7.0x0
to update X86_FEATURE_OSPKE.  cpuid_entry2_find() never returns an entry
for the wrong function.  And not that it matters, but cpuid_entry2_find()
will always return a precise match for CPUID.0x7.0x0 since the index is
significant.

No functional change intended.
