[PATCH v4 5/5] KVM: selftests: Fix typos and stale comments in kvm_util

[Fuad Tabba <tabba@google.com>]

Fix minor documentation errors in `kvm_util.h` and `kvm_util.c`.

- Correct the argument description for `vcpu_args_set` in `kvm_util.h`,
  which incorrectly listed `vm` instead of `vcpu`.
- Fix a typo in the comment for `kvm_selftest_arch_init` ("exeucting" ->
  "executing").
- Correct the return value description for `vm_vaddr_unused_gap` in
  `kvm_util.c` to match the implementation, which returns an address "at
  or above" `vaddr_min`, not "at or below".

No functional change intended.
