Calling error_get_progname() in the context of qemu-io can cause segmentation fault because qemu-io doesn't initialize its progname with error_set_progname(). This patch adds the initialization.
Currently, the missing call of error_set_progname() doesn't cause any problems because qemu-io doesn't use error_get_progname(). This patch is a proactive action.
