minor fixes for stress/crash contruns (#7006)

Browse Source 
Summary:
Avoid using `cf_consistency` together with `enable_compaction_filter` as
the former heavily uses snapshots while the latter is incompatible with
snapshots.

Also fix a clang-analyze error for a write to a variable that is never
read.
