The mlx5_chains_get_table() function doesn't return NULL, it returns
error pointers so we need to fix this condition.

Fixes: 34ca65352ddf ("net/mlx5: E-Switch, Indirect table infrastructure")

This applies to net-next but it might actually go through a different
tree before going to net?  I don't know how this works...
