[committed] Remove stray reference to error_at_rich_loc

[David Malcolm]

"error_at_rich_loc" went away in r254280 (in favor of overloading
"error_at"), but there was a stray reference in a comment.

Remove it.

Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.
Committed to trunk as r265177.

gcc/ChangeLog:
	* gcc-rich-location.h (gcc_rich_location::add_location_if_nearby):
	Fix usage of "error_at_rich_loc" in the comment.
