It turns out that the existing checks do not guarantee that the skb can be
pulled up to the GRO offset. When using the usb r8152 network driver with
GRO fraglist, the BUG() in __skb_pull is often triggered.
Fix the crash by adding the missing check.

Fixes: 8d95dc474f85 ("net: add code for TCP fraglist GRO")
[Suman] Since this is a fix, this should be pushed to "net".

No, it is fixing a commit that was just pulled into -next.
