    netfilter: restore lost ifdef guarding defrag exception
    
    netfilter: restore lost #ifdef guarding defrag exception
    
    Upstream commit 38f7ac3eb:
    
    Nir Tzachar <[EMAIL PROTECTED]> reported a warning when sending
    fragments over loopback with NAT:
    
    [ 6658.338121] WARNING: at net/ipv4/netfilter/nf_nat_standalone.c:89 
nf_nat_fn+0x33/0x155()
    
    The reason is that defragmentation is skipped for already tracked 
connections.
    This is wrong in combination with NAT and ip_conntrack actually had some 
ifdefs
    to avoid this behaviour when NAT is compiled in.
    
    The entire "optimization" may seem a bit silly, for now simply restoring the
    lost #ifdef is the easiest solution until we can come up with something 
better.
