Subject: [PATCH v3 23/57] KVM: x86: Rename kvm_cpu_cap_mask() to kvm_cpu_cap_init()
Rename kvm_cpu_cap_mask() to kvm_cpu_cap_init() in anticipation of merging
it with kvm_cpu_cap_init_kvm_defined(), and in anticipation of _setting_
bits in the helper (a future commit will play macro games to set emulated
feature flags via kvm_cpu_cap_init()).
No functional change intended.
