Use a new REF_STATES_INIT designated initializer instead of assigning to the "strdup_strings" member of the previously memzero()'d version of this struct. The pattern of assigning to "strdup_strings" dates back to 211c89682ee (Make git-remote a builtin, 2008-02-29) (when it was "strdup_paths"), i.e. long before we used anything like our current established *_INIT patterns consistently. Then in e61e0cc6b70 (builtin-remote: teach show to display remote HEAD, 2009-02-25) and e5dcbfd9ab7 (builtin-remote: new show output style for push refspecs, 2009-02-25) we added some more of these. As it turns out we only initialized this struct three times, all the other uses were of pointers to those initialized structs. So let's initialize it in those three places, skip the memset(), and pass those structs down appropriately.
