From: Vlad Buslov <vladbu@mellanox.com>

Modify implementations that return error from action_until->print_aopt()
callback to silently skip actions that don't have their corresponding
TCA_ACT_OPTIONS attribute set (some actions already behave like this). This
is necessary to support terse dump mode in following patch in the series.
