bdrv_img_create() uses qemu_opt_set(), which reports errors with
qerror_report_err(). Its error messages aren't helpful here, the
caller reports one that actually makes sense. I don't know how to
trigger the error conditions, though.
Switch to qemu_opt_set_err() to get rid of the unwanted messages.
