bundle.c: use a temporary variable for OIDs and names

avar · gitster · commit 15e7c7dca66a · 2021-07-06T12:10:16.000-07:00
In preparation for moving away from accessing the OID and name via the
"oid" and "name" slots in a subsequent commit, change the code that
accesses it to use named variables. This makes the subsequent change
smaller.
