commit 6df9defae8435fe7d577ea00350be7db66ee5d2b
from: Omar Polo <op@omarpolo.com>

change got_packidx_match_id_str_prefix not to reset the stailq

Since it appends to the given stailq, the ownership is moved and
so don't initialize/reset it at the start and neither on error.
The caller has to take care of the contents.  (kind of) follow up
to 2234939fb4.

Based upon an original diff from jamsek; ok jamsek
