When both shared and non-shared RSS actions are present in single
flow rule shared RSS index is unset by mistake.
For example:
1. flow indirect_action 0 create action_id 3 ingress action RSS ...
2. set sample_actions 0 mark id 43690 / queue index 0 / end
3. flow create 0 ingress group 107 pattern eth / sample ratio 2
index 0 / indirect 3 / end
PMD translates the indirect action to a shared RSS description at first.
In the split prefix flow, RSS->shared_RSS is unset when translating sample
queue action, the subfix flow will treat the RSS as non-shared.
