Just like the check added to create_flow in 22878dbc9173, comp_mask must be checked in destroy_flow too.
Since only empty comp_mask is currently supported, any other value must be rejected. This check was silently added in a previous patch[1] to move comp_mask in extended command header, part of previous patchset[2] against create/destroy_flow uverbs. The idea of moving comp_mask to the header was discarded for the final patchset[3]. Unfortunately the check added in destroy_flow uverb was not integrated in the final patchset.
