Subject: revert "ipv4: Should use consistent conditional judgement for ip
 fragment in __ip_append_data and ip_finish_output"

This reverts commit f102bb7164c9020e12662998f0fd99c3be72d4f6 which is
commit 0a28cfd51e17f4f0a056bcf66bfbe492c3b99f38 upstream as there is
another patch that needs to be applied instead of this one.
