Subject: [PATCH net] net/mlx5: DR, Fix uninitialized var warning

Smatch warns this:

drivers/net/ethernet/mellanox/mlx5/core/steering/dr_table.c:81
 mlx5dr_table_set_miss_action() error: uninitialized symbol 'ret'.

Fix this by initializing ret with zero.

Fixes: 7838e1725394 ("net/mlx5: DR, Expose steering table functionality")
