Prefer embedded blocks to dedup
Since embedded blocks introduction 11 years ago, their writing was
blocked if dedup is enabled.  After searching through the modern
code I see no reason for this restriction to exist.  Same time
embedded blocks are dramatically cheaper.  Even regular write of
so small blocks would likely be cheaper than deduplication, even
if the last is successful, not mentioning otherwise.
