RDMA/mlx5: Fix error propagation in __mlx5_ib_add

Browse Source 
__mlx5_ib_add() currently returns -ENOMEM on any stage initialization
failure, losing the actual error code returned by the init function.
This makes it impossible for callers to distinguish between different
failure reasons (e.g. -EINVAL, -EIO, -EOPNOTSUPP) and leads to
misleading error handling.

Fix it by returning the actual error code stored in 'err'.
