Memory leak in get_lmbs

[davemq]

In get_lmbs() there's a code path for the case where stat(DYNAMIC_RECONFIG_MEM, &sbuf) fails. In that case, there's this code:

	if (stat(DYNAMIC_RECONFIG_MEM, &sbuf)) {
		struct dr_connector *drc_list, *drc;

		drc_list = get_drc_info(OFDT_BASE);

drc_list is never freed in this code.

I don't know if this is ever seen in practice. Given drmgr is typically a short-lived process, this may be a low priority to fix.

Yeah, in general being a short lived process we know the memory will get cleaned up for us when the process dies, but nothing wrong with being pedantic seeing as its just good practice in general.
