tracing: Fix uninitialized variable of tracing/trace output
Because a local variable is not initialized, I got these
when I did 'cat tracing/trace'. (not trace_pipe):
CPU:0 [LOST 18446744071579453134 EVENTS]
ps-3099 [000] 560.770221: lock_acquire: ffff880030865010 &(&dentry->d_lock)->rlock
CPU:0 [LOST 18446744071579453134 EVENTS]
ps-3099 [000] 560.770221: lock_release: ffff880030865010 &(&dentry->d_lock)->rlock
CPU:0 [LOST 18446612133255294080 EVENTS]

ps-3099 [000] 560.770222: lock_release: ffffffff816cfb98 dcache_lock
See peek_next_entry(), it does not set *lost_events when we 'cat tracing/trace'
