[libvirt] [PATCH] plug two sound-related leaks

[Jim Meyering <jim@xxxxxxxxxxxx>]

This fixes the sole remaining leak exposed by "make check" vs. valgrind.
Actually it fixes two leaks, but the duplicate sound string one
isn't triggered by the tests.

Subject: [PATCH] plug two sound-related leaks

* src/qemu_conf.c (qemudFreeVMDef): Also free def->sounds.
(qemudParseXML): Avoid leak also for duplicate sound string.
