ipv4: Don't pass IP fragments to upper layer GRO handlers.
Upper layer GRO handlers can not handle IP fragments, so
exit GRO processing in this case.
This fixes ESP GRO because the packet must be reassembled
before we can decapsulate, otherwise we get authentication
failures.
It also aligns IPv4 to IPv6 where packets with fragmentation
headers are not passed to upper layer GRO handlers.
Fixes: 7785bba299a8 ("esp: Add a software GRO codepath")
