KVM: x86/mmu: Directly "destroy" PTE list when recycling rmaps
Browse files Browse the repository at this point in the history
Use pte_list_destroy() directly when recycling rmaps instead of bouncing
through kvm_unmap_rmapp() and kvm_zap_rmapp().  Calling kvm_unmap_rmapp()
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.
