netfilter: nf_tables: use kzalloc for hook allocation

Browse Source 
[ 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.
