Mikulas Patocka b716ccffbc dm writecache: write at least 4k when committing ...

commit 867de40c4c upstream.

SSDs perform badly with sub-4k writes (because they perfrorm
read-modify-write internally), so make sure writecache writes at least
4k when committing.

Fixes: 991bd8d7bc ("dm writecache: commit just one block, not a full page")
