packfile: stop using linked MIDX list in find_pack_entry()

Browse Source 
Refactor `find_pack_entry()` so that we stop using the linked list of
multi-pack indices. Note that there is no need to explicitly prepare
alternates, and neither do we have to use `get_multi_pack_index()`,
because `prepare_packed_git()` already takes care of populating all data
structures for us.
