[PATCH 13/19] transport.c: remove implicit dependency on the_index

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

note, there's still another hidden dependency related to this: even
though we pass a repo to transport_push() we still use
is_bare_repository() which pretty much assumes the_repository (and
some other global state).
