nbd: implement bdrv_get_info callback
Since mirror job supports efficient zero out target mechanism (see in mirror_dirty_init()), implement bdrv_get_info to make it work over NBD. Such improvement will allow using the largest chunk possible and will decrease the number of NBD_CMD_WRITE_ZEROES requests on the wire.
