flow: Split flow_extract

Browse Source 
Split the L3 and above portion of flow_extract() out into
flow_extract_l3_onwards() and call flow_extract_l3_onwards()
from flow_extract().

This is to allow re-extraction of l3 and higher information using
flow->encap_dl_type which may be set using information contained
in actions.
