[libvirt] [PATCH] fix memory leak in daemonUnixSocketPaths and qemuMonitorJSONAttachCharDevCommand

[Yi Wang]

From: Xi Xu <xu.xi8 at zte.com.cn>

The @rundir is allocated in virGetUserRuntimeDirectory, may lost
when virFileMakePath failed.

The tlsalias allocated in qemuAliasTLSObjFromSrcAlias may lost
when append string to json.
