perf report: Fix NULL pointer dereference in hists__fprintf_nr_sample_events()
[ Upstream commit 11b6e5482e178055ec1f2444b55f2518713809d1 ]
The 'evname' variable can be NULL, as it is checked a few lines back,
check it before using.
Fixes: 9e207ddfa207 ("perf report: Show call graph from reference events")
