I found another...

linux-thread-db.c initializes td_ta_map_id2thr but never uses it.
This commit removes this dead code.

Pushed as obvious.

gdb/ChangeLog:

	* linux-thread-db.c (struct thread_db_info)
	<td_ta_map_id2thr_p>: Remove field.
	(try_thread_db_load_1): Remove initialization for the above.
