[PATCH 3/4] cat-file: restore ambiguity warning flag in batch_objects

[Jeff King <peff@peff.net>]

Since commit 25fba78, we turn off the object/refname
ambiguity warning using a global flag. However, we never
restore it. This doesn't really matter in the current code,
since the program generally exits immediately after the
function is done, but it's good code hygeine to clean up
after ourselves.
