Fix the failure semantics of procfs_make_node
* procfs.c (procfs_make_node): Invoke the cleanup callback on failure, so that callers don't have to. * procfs.h: Document the change. * procfs_dir.c (procfs_dir_make_node), procfs_file.c (procfs_file_make_node), proclist.c (proclist_make_node): Update to reflect the change.
