net/mlx5: handle errors in mlx5_chains_create_table()

Browse source

[ Upstream commit eab0396353 ]

In mlx5_chains_create_table(), the return value of mlx5_get_fdb_sub_ns()
and mlx5_get_flow_namespace() must be checked to prevent NULL pointer
dereferences. If either function fails, the function should log error
message with mlx5_core_warn() and return error pointer.
