[PATCH rdma-next 05/14] RDMA/uverbs: Return not supported error code for unsupported commands

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Leon Romanovsky <leonro-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

Command that doesn't exist means that it is not supported,
so update code to return -EOPNOTSUPP in case of failure.
