[PATCH nf-next v2 21/30] netfilter: wrap inline synproxy function in CONFIG_NETFILTER_SYNPROXY check.

[Jeremy Sowden]

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.
