losetup: properly use --sector-size when create a new device
The --partscan functionality depends on sector size. Make sure
sector size is set before we force kernel to scan the device for
partitions. For example:
losetup -f loopfile --sector-size 4KiB --partscan --show
where 'loopfile' contains GPT with 4096 sectors.
