net/sched: flower: add missing validation of TCA_FLOWER_FLAGS
[ Upstream commit5.4-rM2-2.2.x-imx-squashede2debf0852
] 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:5b33f48842
