tools/thermal: tmon: silence 'set but not used' warnings
gcc complains about the 'cols' variable being unused. This is
unavoidable, given the ncurses getmaxyx() macro-based API, which wants
to assign to a variable directly, even when we're not going to use it.
Warning:
gcc -O1 -Wall -Wshadow -W -Wformat -Wimplicit-function-declaration -Wimplicit-int -fstack-protector -D VERSION=\"1.0\" -c -o tui.o tui.c
tui.c: In function ‘show_dialogue’:
tui.c:288:12: warning: variable ‘cols’ set but not used [-Wunused-but-set-variable]
int rows, cols;
^
So, add a hack to get rid of that warning.
