soliddevice: Use KDiskFreeSpaceInfo instead of solid to get disk size
Review Request #123818 - Created May 16, 2015 and submitted
Currently, the size of devices is retrieved with solid.
Unfortunately, it doesn't work for network shares. Only the "StorageVolume" type has the "size" option.
KDiskFreeSpaceInfo supports every mounted device, not matter its type.
Tested with local disks, USB devices, NFS shares
Refactoring of the free space update code.
