Use bdrv_pwrite to access the backing device instead of pread, and convert the driver to implementing the bdrv_open method which gives it an already opened BlockDriverState for the underlying device. Dmg actually does an lseek to a negative offset in the open routine, which we replace with offset arithmetics after doing a bdrv_getlength.
