is_rmap_spte(), originally named is_rmap_pte(), was introduced when the
simple reverse mapping was implemented by commit cd4a4e5374
("[PATCH] KVM: MMU: Implement simple reverse mapping"). At that point,
its role was clear and only rmap_add() and rmap_remove() were using it
to select sptes that need to be reverse-mapped.
Independently of that, is_shadow_present_pte() was first introduced by
commit c7addb9020 ("KVM: Allow not-present guest page faults to
bypass kvm") to do bypass_guest_pf optimization, which does not exist
any more.
These two seem to have changed their roles somewhat, and is_rmap_spte()
just calls is_shadow_present_pte() now.
Since using both of them without clear distinction just makes the code
confusing, remove is_rmap_spte().
