tracing: Remove unused variable in trace_benchmark

Somehow this unused variable warning sneaked past my warnings check
(probably due to it depending on a new config).

kernel/trace/trace_benchmark.c: In function 'trace_do_benchmark':
kernel/trace/trace_benchmark.c:38:6: warning: unused variable 'seedsq' [-Wunused-variable]
  u64 seedsq;
      ^
