From: Florian Westphal fw@strlen.de
[ Upstream commit 195e5f88c2e48330ba5483e0bad2de3b3fad484f ]
KMSAN reports unitialized variable when registering the hook, reg->hook_ops_type == NF_HOOK_OP_BPF) ~~~~~~~~~~~ undefined
This is a small structure, just use kzalloc to make sure this won't happen again when new fields get added to nf_hook_ops.
