[PATCH v2 2/6] midx-write: put failing response value back

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <stolee@gmail.com>

This instance of setting the result to 1 before going to cleanup was
accidentally removed in fcb2205b77 (midx: implement support for writing
incremental MIDX chains, 2024-08-06). Build upon a test that already deletes
a packfile to verify that this error propagates to full command failure.
