kvm tools: Free vcpu array on shutdown

This patch silences the following harmless warning to reduce valgrind noise:

  ==5529== 864 bytes in 3 blocks are possibly lost in loss record 39 of 48
  ==5529==    at 0x4A04B84: calloc (vg_replace_malloc.c:467)

  ==5529==    by 0x3DE682139C: (below main) (in /lib64/libc-2.14.so)
