While running qemuhotplugtest, it was found that valgrind pointed out
the following memory leak:
==7906== 5 bytes in 1 blocks are definitely lost in loss record 7 of 121
==7906== at 0x4A069EE: malloc (vg_replace_malloc.c:270)
==7906== by 0x3E782A754D: xmlStrndup (in /usr/lib64/libxml2.so.2.7.6)
==7906== by 0x4CDAE03: virDomainDeviceInfoParseXML.isra.32 (domain_conf.c:3685)
==7906== by 0x4CE3BB9: virDomainNetDefParseXML (domain_conf.c:6707)
==7906== by 0x4CFBA08: virDomainDefParseXML (domain_conf.c:12235)
==7906== by 0x4CFBC1E: virDomainDefParseNode (domain_conf.c:13039)
==7906== by 0x4CFBD95: virDomainDefParse (domain_conf.c:12981)
==7906== by 0x41FEB4: testQemuHotplug (qemuhotplugtest.c:66)
==7906== by 0x420F41: virtTestRun (testutils.c:201)
==7906== by 0x41F287: mymain (qemuhotplugtest.c:422)
==7906== by 0x4216BD: virtTestMain (testutils.c:784)
==7906== by 0x3E6CE1ED1C: (below main) (libc-start.c:226)
...and 10 more.
The 'alias' attribute should *not* be parsed from the XML provided by
the user. It should only be parsed in the live state XML. In the latter
case no codepath should take us to qemuAssignDeviceAliases (which, in
this case, is causing the above leaks).

Caused by the test cases:
DO_TEST_ATTACH("console-compat-2", "console-virtio", false, true,
"chardev-add", "{\"return\": {\"pty\": \"/dev/pts/26\"}}",
"device_add", QMP_OK);
DO_TEST_DETACH("console-compat-2", "console-virtio", false, false,
"device_del", QMP_OK,
"chardev-remove", QMP_OK);
