Subject: [PATCH v2 4/7] KVM: x86/mmu: Rename __kvm_zap_rmaps() to align with
 other nomenclature

Rename __kvm_zap_rmaps() to kvm_rmap_zap_gfn_range() to avoid future
confusion with a soon-to-be-introduced __kvm_zap_rmap().  Using a plural
"rmaps" is somewhat ambiguous without additional context, as it's not
obvious whether it's referring to multiple rmap lists, versus multiple
rmap entries within a single list.

Use kvm_rmap_zap_gfn_range() to align with the pattern established by
kvm_rmap_zap_collapsible_sptes(), without losing the information that it
zaps only rmap-based MMUs, i.e. don't rename it to __kvm_zap_gfn_range().

No functional change intended.
