Subject: [PATCH 4/5] KVM: x86/mmu: Use innermost rmap zap helper when
 recycling rmaps

Use ____kvm_zap_rmaps() directly when recycling rmaps instead of bouncing
through kvm_zap_rmaps() and __kvm_zap_rmaps().  Calling kvm_zap_rmaps()
is unnecessary and odd as it requires passing dummy parameters; passing
NULL for @slot when __rmap_add() already has a valid slot is especially
weird and confusing.

No functional change intended.
