[PATCH v2 1/5] pack-bitmap.c: continue looping when first MIDX bitmap is found

[Teng Long <dyroneteng@gmail.com>]

In "open_midx_bitmap()", we do a loop with the MIDX(es) in repo, when
the first one has been found, then will break out by a "return"
directly.

But actually, it's better to don't stop the loop until we have visited
both the MIDX in our repository, as well as any alternates (along with
_their_ alternates, recursively).
