net: ipa: IPA status preparatory cleanups
The next patch reworks how the IPA packet status structure is
interpreted. This patch does some preparatory work, to make it
easier to see the effect of that change:
- Change a few functions that access fields in a IPA packet status
structure to store field values in local variables with names
related to the field.
- Pass a void pointer rather than an (equivalent) status pointer
to two functions called by ipa_endpoint_status_parse().
- Use "rule" rather than "val" as the name of a variable that
holds a routing rule ID.
- Consistently use "IPA packet status" rather than "status
element" when referring to this data structure.
