[IPV4]: Make ip_defrag return the same packet

Browse source

This patch is a bit of a hack.  However it is worth it if you consider that
this is the only reason why we have to carry around the struct sk_buff **
pointers in netfilter.

It makes ip_defrag always return the packet that was given to it on input.
It does this by cloning the packet and replacing its original contents with
the head fragment if necessary.
