At least old Xen net backends seem to send frags with no real data sometimes. In case such a fragment happens to occur with the frag limit already reached the frontend will BUG currently even if this situation is easily recoverable.
Modify the BUG_ON() condition accordingly.

Applied and queued up for -stable.
But many of these BUG's in the driver should be converted to WARNs and recovery code added.
