Ian Rogers 3d1d029734 perf stat: Avoid metric-only segv 
[ Upstream commit 2543947c77 ]

Cycles is recognized as part of a hard coded metric in stat-shadow.c,
it may call print_metric_only with a NULL fmt string leading to a
segfault. Handle the NULL fmt explicitly.

Fixes: 088519f318 ("perf stat: Move the display functions to stat-display.c")
