Remove unnecessary calls to is_mi_like_p in print_thread_info_1

There are two calls to uiout->is_mi_like_p in the else branch of a
if (uiout->is_mi_like_p ()), we already know they will return false.

A bit lower, there are two if (!uiout->is_mi_like_p ()) that we can
merge.

gdb/ChangeLog:

	* thread.c (print_thread_info_1): Remove unnecessary calls to
	uiout->is_mi_like_p.
