nf_conntrack_synproxy.h contains three inline functions. The contents
of two of them are wrapped in CONFIG_NETFILTER_SYNPROXY checks and just
return NULL if it is not enabled. The third does nothing if they return
NULL, so wrap its contents as well.
nf_ct_timeout_data is only called if CONFIG_NETFILTER_TIMEOUT is
enabled. Wrap its contents in a CONFIG_NETFILTER_TIMEOUT check like the
other inline functions in nf_conntrack_timeout.h.
