[PATCH net 1/3] net/mlx5: HWS, Handle NULL in vport destination action creation

[Tariq Toukan <tariqt@nvidia.com>]

From: Yevgeny Kliteynik <kliteyn@nvidia.com>

mlx5hws_action_create_dest_vport can return NULL - handle
this case before trying to insert NULL into xarray.

Fixes: 8e2e08a6d1e0 ("net/mlx5: fs, add support for dest vport HWS action")
