[PATCH v2 09/13] server-info: simplify cleanup in parse_pack_def()

[Jeff King]

We have two exits from the function: either we jump to the out_stale
label or not. But in both exits we repeat our cleanup, and the only
difference is our return value. Let's just use a variable for the return
value to avoid repeating ourselves.
