iomap: Switch from blkno to disk offset
Replace iomap->blkno, the sector number, with iomap->addr, the disk offset in bytes. For invalid disk offsets, use the special value IOMAP_NULL_ADDR instead of IOMAP_NULL_BLOCK. This allows to use iomap for mappings which are not block aligned, such as inline data on ext4.
