Clang warns:
drivers/net/ethernet/mellanox/mlx5/core/en/tc/sample.c:635:34: error: variable 'esw' is uninitialized when used here [-Werror,-Wuninitialized]
mlx5_eswitch_del_offloaded_rule(esw, sample_flow->pre_rule, sample_flow->pre_attr);

struct mlx5_eswitch *esw;

= NULL
1 error generated.
It appears that the assignment should have been shuffled instead of
removed outright like in mlx5e_tc_sample_offload(). Add it back so there
is no use of esw uninitialized.
