ipsw: Fix concurrent access to ZIP fileHEADmaster

With the new AsyncDataRequestMsg we have the problem that
multiple threads would access the .ipsw, however we were
only using one struct zip* handle for the entire procedure,
resulting in read errors when concurrent access occurs.
This commit fixes it by opening the zip file for every access
separately.
