dm snapshot: flush disk cache when merging
commit 762a80d9fc9f690a3a35983f3b4619a220650808 upstream.
This patch makes dm-snapshot flush disk cache when writing metadata for
merging snapshot.
Without cache flushing the disk may reorder metadata write and other
data writes and there is a possibility of data corruption in case of
power fault.
