net/sched: flower: add missing validation of TCA_FLOWER_FLAGS
unlike other classifiers that can be offloaded (i.e. users can set flags
like 'skip_hw' and 'skip_sw'), 'cls_flower' doesn't validate the size of
netlink attribute 'TCA_FLOWER_FLAGS' provided by user: add a proper entry
to fl_policy.
Fixes: 5b33f48842fa ("net/flower: Introduce hardware offload support")
