[PATCH 05/10] KVM: x86: Rename get_msr_feature() APIs to get_feature_msr()

[Sean Christopherson <seanjc@google.com>]

Rename all APIs related to feature MSRs from get_feature_msr() to
get_feature_msr().  The APIs get "feature MSRs", not "MSR features".
And unlike kvm_{g,s}et_msr_common(), the "feature" adjective doesn't
describe the helper itself.

No functional change intended.
