kho: cleanup error handling in kho_populate()

* use dedicated labels for error handling instead of checking if a pointer
  is not null to decide if it should be unmapped
* drop assignment of values to err that are only used to print a numeric
  error code, there are pr_warn()s for each failure already so printing a
  numeric error code in the next line does not add anything useful
