net/sched: matchall: add missing validation of TCA_MATCHALL_FLAGS
[ Upstream commit 1afa3cc90f8fb745c777884d79eaa1001d6927a6 ]
unlike other classifiers that can be offloaded (i.e. users can set flags
like 'skip_hw' and 'skip_sw'), 'cls_matchall' doesn't validate the size
of netlink attribute 'TCA_MATCHALL_FLAGS' provided by user: add a proper
entry to mall_policy.
Fixes: b87f7936a932 ("net/sched: Add match-all classifier hw offloading.")
