[libvirt] [PATCH 08/17] Fix leak on OOM in qemuBuildCommandLine dealing with sound card

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

The qemuBuildCommandLine code for parsing sound cards will leak
an intermediate variable if an OOM occurs. Move the free'ing of
the variable earlier to avoid the leak.
