In order to avoid external dependencies on implementation details,
this change replaces RBDError with the unexported rbdError. 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() ... }
