net/mlx5: Fix memory leak in esw_acl_ingress_lgcy_setup()

In esw_acl_ingress_lgcy_setup(), if esw_acl_table_create() fails,
the function returns directly without releasing the previously
created counter, leading to a memory leak.

Fix this by jumping to the out label instead of returning directly,
which aligns with the error handling logic of other paths in this
function.

Compile tested only. Issue found using a prototype static analysis tool
and code review.
