Mikulas Patocka 45354f1eb6 dm bufio: don't embed a bio in the dm_buffer structure ... The bio structure consumes a substantial part of dm_buffer. The bio structure is only needed when doing I/O on the buffer, thus we don't have to embed it in the buffer. Allocate the bio structure only when doing I/O. We don't need to create a bio_set because, in case of allocation failure, dm-bufio falls back to using dm-io (which keeps its own bio_set).
