[PATCH-RUBY] The first argument passed should be the disk not the size.

[Marius Rieder <marius.rieder@xxxxxxx>]

Calling block_resize on a Libvirt::Domain object leads to a TypeError.
The reason seems to be that ruby-libvirt tries to convert the size
instead of the disk to a string to pass as the disk parameter.
