Small optimization in Block Device driver

Method _devices_sizes() in Block Device driver invokes N times
_get_device_size(device) to get devices sizes. It can be done by
executing one command: blockdev --getsize64 /dev/loop1 /dev/loop2.
In such a way we take the devices' sizes in bytes and convert them
to Megabytes.
