Dmitry Vyukov ad10785a70 netfilter: x_tables: fix pointer leaks to userspace 
[ Upstream commit 1e98ffea5a8935ec040ab72299e349cb44b8defd ]

Several netfilter matches and targets put kernel pointers into
info objects, but don't set usersize in descriptors.
This leads to kernel pointer leaks if a match/target is set
and then read back to userspace.

Properly set usersize for these matches/targets.

Found with manual code inspection.

Fixes: ec2318904965 ("xtables: extend matches and targets with .usersize")
