bridge: Clear INET control block of SKBs passed into ip_fragment().
In a similar vain to commit 17762060c25590bfddd68cc1131f28ec720f405f ("bridge: Clear IPCB before possible entry into IP stack") Any time we call into the IP stack we have to make sure the state there is as expected by the ipv4 code. With help from Eric Dumazet and Herbert Xu. Reported-by: Bandan Das <bandan.das@stratus.com> Signed-off-by: David S. Miller <davem@davemloft.net>
