Subject: [PATCH 6/6] fix virsh commands' message for memtune'swap_hard_limit.

cgroup's /cgroup/memory/memory.memsw.limit_in_bytes is not
for limitinit 'swap' but for 'memory+swap' (then, it's memsw)
(So, this number cannot be smaller than memory.limit_in_bytes)

Note:
If other hypervisors than Linux support this and meaning is
not same as memory+swap, the name swap_hard_limit will have confusion.
