The 'rbd_image_spec_t' struct has two string members 'id' and 'name'. We only stole the 'name' members thus the 'id's as well as the whole list would be leaked on success. Restructure the code so that we copy out the image names and call rbd_image_spec_list_cleanup on success rather than on error. The error path is then handled by using g_autofree for 'images'. Since we no longer have a error path after allocating the returned string list we can completely remove it's cleanup.

Use automatic memory freeing for the string list so that we can remove the cleanup section.
