Daniel T. Lee 335d4f8182 samples: bpf: fix: seg fault with NULL pointer arg
[ Upstream commit d59dd69d55 ]

When NULL pointer accidentally passed to write_kprobe_events,
due to strlen(NULL), segmentation fault happens.
Changed code returns -1 to deal with this situation.

Bug issued with Smatch, static analysis.
