Rename kvm_unmap_rmap() and kvm_zap_rmap() to kvm_zap_rmap() and
__kvm_zap_rmap() respectively to show that what was the "unmap" helper is
just a wrapper for the "zap" helper, i.e. that they do the exact same
thing, one just exists to deal with its caller passing in more params.

No functional change intended.
