REDHAT-BUG-726552: Medium severity red hat linux vulnerability
Currently skbgroheaderslow unconditionally resets frag0 and frag0len. However, when we can't pull on the skb this leaves the GRO fields in an inconsistent state.
This patch fixes this by only resetting those fields after the pskbmaypull test.
