net/mlx5: fix flow indirect action reference counting

net/mlx5: fix flow indirect action reference counting

When an indirect action is used in a flow rule with a pattern that
causes RSS expansion, each device flow generated by the expansion
incremented the reference counter of the action. When such a flow was
destroyed, its action reference counter had been decremented only once.
The action remained marked as being used and could not be destroyed.
COUNT, AGE, and CONNTRACK indirect actions have been affected
(for AGE the error was not immediately observable).
Increment action counter only once for the original flow rule.
