netfilter: nf_conntrack: silence warning on falling back to vmalloc()

Since 88eab472ec21 ("netfilter: conntrack: adjust nf_conntrack_buckets default
value"), the hashtable can easily hit this warning. We got reports from users
that are getting this message in a quite spamming fashion, so better silence
this.
