Currently iohelper's error log is recorded in virFileWrapperFdClose.
In qemuDomainSaveMemory, it usually fails at qemuMigrationSrcToFile,
and then goto cleanup, so the iohelper error log is not recorded,
and so is the another placement. We now record the error log of
iohelper by move it to the virFileWrapperFdFree record.
There is another problem here, that is, virCommandWait is also not
called, but I can't evaluate this impact. So no changes have been
made here.
