Diagnostic output goes to stderr, except when we're in a monitor command, when it goes to the monitor instead. config_error() implements this with a monitor argument: if it's non-null, report there, else to stderr. This obliges us to pass the monitor down various call chains, to make it available to config_error(). The recently created qemu_error() doesn't need a monitor argument to route output. Use it. There's one user-visible difference: config_error() prepended "qemu: " to a message bound for stderr. qemu_error() doesn't, which means the prefix goes away with this commit. If such a prefix is desired for stderr, then I figure it should be slapped on all error messages, not just the ones that used to go through config_error().
