Re: [libvirt] [PATCH] qemu: fix lastError memory leak

When an error occurred in qemuMonitorIO, it will be saved in mon->lastError, but the memory which mon->lastError.message, mon->lastError.str1, mon->lastError.str2 and mon->lastError.str3 will not be freed at last. The same bug happened in qemuAgentIO. So I add the following code to fix it.
