[libvirt] [PATCH] fix a realloc problem

[Daniel Veillard]

  The xen code for detaching devices had a mistake in the
resize compaction code, the size of the data copied was improper,
moving N bytes, instead of sizeof(device) * N  bytes.

  The attached patch by Dan Berrange fixes it, it's trivial
so I commited it,

Daniel
