Mikulas Patocka 762a80d9fc dm snapshot: flush disk cache when merging ...

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.
