bees: clean up #if 0 ... fsync ... #endif code

Browse Source 
Remove some dead code because dedup-related deadlocks have not been
observed since Linux kernel v4.11.

Preserve rationale of remaining #if 0 block (why we do write/rename
instead of write/fsync/rename) so that people don't try to replace the
"missing" fsync() there.
