CVE: NA

------------------------------

The recently pushd bugfix patch "Delay to invalidate cache data
in writearound write" has a stupid copy&paste bug, which causes
bypassed write request will never invalidate data in cache device,
causing a data corruption. This patch fixes this corruption.
This patch also ensures that the writeback lock is released after
data insert.

Fixes: 6a1d9c41b367 ("bcache: Delay to invalidate cache data in writearound write")
