odp-util: Pass down flow netlink attributes when translating masks.

Browse Source 
Sometimes we need to look at flow fields to understand how to parse
an attribute. However, masks don't have this information - just the
mask on the field. We already use the translated flow structure for
this purpose but this isn't always enough since sometimes we actually
need the raw netlink information. Fortunately, that is also readily
available so this passes it down from the appropriate callers.
