netfilter: synproxy: ensure zero is returned on non-error return path 

Currently functions nf_synproxy_{ipc4|ipv6}_init return an uninitialized
garbage value in variable ret on a successful return.  Fix this by
returning zero on success.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: d7f9b2f18e ("netfilter: synproxy: extract SYNPROXY infrastructure from {ipt, ip6t}_SYNPROXY")
