[PATCH v7 04/16] reftable: check reftable_stack_auto_compact() return value

["Han-Wen Nienhuys via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Han-Wen Nienhuys <hanwen@xxxxxxxxxx>

If compaction consistently errors out, we would accumulate reftables,
and the follow-on EXPECT would start failing, but catching errors
early helps debugging.
