gdb: Simplify parse_frame_specification.

Remove an unneeded parameter from parse_frame_specification, replace
with a fixed string within parse_frame_specification.  The message was
the same in every place that parse_frame_specification was used anyway.

gdb/ChangeLog:

	* stack.c (parse_frame_specification): Remove message parameter,
	replace with fixed string in function body, update function
	comment.
	(frame_info): Remove message to parse_frame_specification.
	(select_frame_command): Likewise.
