From: Leon Romanovsky <leo...@mellanox.com> In the accepted series "Refactor ib_uverbs_write path", we presented the roadmap to get rid of uverbs_cmd_mask and uverbs_ex_cmd_mask fields in favor of simple check of function pointer. So let's put NULL check of create_flow function callback despite the fact that uverbs_ex_cmd_mask still exists.
