Subject: [net-next 13/15] net/mlx5: CT: Remove extra rhashtable remove on tuple entries

From: Paul Blakey <paulb@...dia.com>

On tuple offload del command, tuples are tried to be removed twice
from the hashtable, once directly via mlx5_tc_ct_entry_remove_from_tuples()
and a second time in the following mlx5_tc_ct_entry_put()->
mlx5_tc_ct_entry_del()->mlx5_tc_ct_entry_remove_from_tuples() call.

This doesn't cause any issue since rhashtable first checks if the
removed object exists in the hashtable.

Remove the extra mlx5_tc_ct_entry_remove_from_tuples().
