GetParentInfo() currently requires the caller to specify the
string length for various attributes it returns. If the
specified string length is less than required, it can return
ERANGE error. Replacing it with a new function which avoids
this.

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() ... }
