[libvirt] [PATCH] plug two leaks and fix a diagnostic

[Jim Meyering]

Without this patch, running make check would trigger this minor leak:

  10 bytes in 1 blocks are definitely lost in loss record 1 of 20
     at 0x4A0739E: malloc (vg_replace_malloc.c:207)
     by 0x3F872808A1: strdup (strdup.c:43)
     by 0x4CA2503: qemudLoadDriverConfig (qemu_conf.c:70)
     by 0x4CA7EA7: qemudStartup (qemu_driver.c:216)
     by 0x4C3AEBC: __virStateInitialize (libvirt.c:592)
     by 0x4096B6: qemudInitialize (qemud.c:738)
     by 0x40CCCF: main (qemud.c:2216)

Looking into it, I found there were actually two separate leaks
and an erroneous diagnostic.  This fixes them:

* src/qemu_conf.c (qemudLoadDriverConfig): Don't leak ->vncListen.
Fix an erroneous copy-and-pasted diagnostic.
* src/qemu_driver.c (qemudShutdown): Don't leak another ->vncListen.
