The recent push to use correct scaling terms (kB for 1000, KiB for
1024 - such as commit 9dfdead) missed some places in virsh.
* tools/virsh.c (prettyCapacity, cmdDominfo, cmdFreecell)
(cmdNodeinfo, cmdNodeMemStats, cmdMigrateSetMaxSpeed)
(cmdBlockCopy, cmdBlockPull, cmdBlockJob): Use KiB, not kB, when
referring to multiples of 1024.
* tests/virshtest.c: Update expected output to match.
