Syzbot reported warning in netlbl_cipsov4_add(). The
problem was in too big doi_def->map.std->lvl.local_size
passed to kcalloc(). Since this value comes from userpace there is
no need to warn if value is not correct.

The same problem may occur with other kcalloc() calls in
this function, so, I've added __GFP_NOWARN flag to all
kcalloc() calls there.

Hi, net developers!

Is this patch merged somewhere? I've checked net tree and Paul Moore
tree on https://git.kernel.org/, but didn't find it. Did I miss it
somewhere? If not, it's just a gentle ping :)

Btw: maybe I should send it as separete patch, since 2/2 in this
series is invalid as already in-tree?

I'm not sure why this hasn't been picked up yet, but I suppose
resubmitting just this patch couldn't hurt.  Don't forget to include
my ACK if you do.
