flow_dissector: Fix unaligned access in __skb_flow_dissector when used by eth_get_headlen
This patch fixes an issue with unaligned accesses when using
eth_get_headlen on a page that was DMA aligned instead of being IP aligned.
The fact is when trying to check the length we don't need to be looking at
the flow label so we can reorder the checks to first check if we are
supposed to gather the flow label and then make the call to actually get
it.
v2: Updated path so that either STOP_AT_FLOW_LABEL or KEY_FLOW_LABEL can
cause us to check for the flow label.
