net/mlx5: Geneve, Fix handling of Geneve object id as error code

Browse Source 
[ Upstream commit d28a06d7dbedc598a06bd1e53a28125f87ca5d0c ]

On success, mlx5_geneve_tlv_option_create returns non negative
Geneve object id. In case the object id is positive value the
caller functions will handle it as an error (non zero) and
will fail to offload the Geneve rule.

Fix this by changing caller function ,mlx5_geneve_tlv_option_add,
to return 0 in case valid non negative object id was provided.
