[PATCH] qemu: Don't regenerate NVRAM path if parsed from domain XML

After v8.0.0-466-g08101bde5d we unconditionally regenerate per domain NVRAM path even though it might have been parsed earlier from domain XML. The way we do that leads to a memleak: 43 bytes in 1 blocks are definitely lost in loss record 330 of 682 at 0x483F7E5: malloc (vg_replace_malloc.c:381) by 0x50D5B18: g_malloc (in /usr/lib64/libglib-2.0.so.0.7000.2) by 0x50EFA4F: g_strdup (in /usr/lib64/libglib-2.0.so.0.7000.2) by 0x49E774E: virXPathString (virxml.c:88) by 0x4A3F0E4: virDomainDefParseBootLoaderOptions (domain_conf.c:18226) by 0x4A3F49C: virDomainDefParseBootOptions (domain_conf.c:18298) by 0x4A448C3: virDomainDefParseXML (domain_conf.c:19598) by 0x4A487A1: virDomainDefParseNode (domain_conf.c:20404) by 0x117FCF: testCompareXMLToArgv (qemuxml2argvtest.c:726) by 0x142124: virTestRun (testutils.c:142) by 0x1423D4: virTestRunLog (testutils.c:197) by 0x140A76: mymain (qemuxml2argvtest.c:3406) If we parsed NVRAM path from domain XML we must refrain from generating new path.
