make find_pack_revindex() aware of the nasty world

Browse Source 
It currently calls die() whenever given offset is not found thinking
that such thing should never happen.  But this offset may come from a
corrupted pack whych _could_ happen and not be found.  Callers should
deal with this possibility gracefully instead.
