Fix some comments related to library unloading
Library unloading has never been supported with its code removed in
ab02d702ef08, and there were some comments still mentioning that it was
a possible operation.
ChangAo has noticed the incorrect references in dfmgr.c, while I have
noticed the other ones while scanning the rest of the tree for similar
mistakes.
