Arnaldo Carvalho de Melo ed847e30f0 perf test bpf: Address error about non-null argument for epoll_pwait 2nd arg
First noticed on Fedora Rawhide:

  tests/bpf.c: In function ‘epoll_pwait_loop’:
  tests/bpf.c:36:17: error: argument 2 null where non-null expected [-Werror=nonnull]
     36 |                 epoll_pwait(-(i + 1), NULL, 0, 0, NULL);
        |                 ^~~~~~~~~~~
  In file included from tests/bpf.c:5:
  /usr/include/sys/epoll.h:134:12: note: in a call to function ‘epoll_pwait’ declared ‘nonnull’
    134 | extern int epoll_pwait (int __epfd, struct epoll_event *__events,
