Add a new error that will be returned from a op step method if the
method is called before the step is ready to provide data - like
when the operation has not yet been performed.

In order to avoid external dependencies on implementation details,
this change replaces RadosError with the unexported radosError. In case
some application really needs access to the integer value, it can use
the pattern
var errno interface{ Errno() int }
if errors.As(err, errno) { ... errno.Errno() ... }
