In situations as such, Namaz will be considered valid even by standing back to recite Qunoot, after going to Ruku’u or straightaway making Sajda Sahw at the end without reciting Qunoot after Ruku. However if Ruku is performed back and at the end of Namaz if Sajda Sahw too is performed, still, the Namaz is valid but should avoid doing so.
