Changelog entry
Fixed a race between table merge and borrowed gc compaction.

Additional information
A fix in #2286 introduced a race, where datashard allowed local database to compact borrowed data before all borrowed data is actually loaded and merged into the table. This caused local database borrowed compaction to later fail due to unexpected epoch invariant violations.
Fixes #3154.
