Konstantin Ananyev 7f0983ee33 ip_frag: check fragment length of incoming packet 
Under some conditions ill-formed fragments might cause
reassembly code to corrupt mbufs and/or crash.
Let say the following fragments sequence:
<ofs=0,len=100, flags=MF>
<ofs=96,len=100, flags=MF>
<ofs=200,len=0,flags=MF>
<ofs=200,len=100,flags=0>
can trigger the problem.
To overcome such situation, added check that fragment length
of incoming value is greater than zero.

Fixes: 601e279df0 ("ip_frag: move fragmentation/reassembly headers into a library")
Fixes: 4f1a8f6338 ("ip_frag: add IPv6 reassembly")
