Suren Baghdasaryan 5d96c24be9 ANDROID: uid_sys_stats: defer process_notifier work if uid_lock is contended ...

process_notifier() is called every time a process exits. When multiple
processes exit roughly at the same time, the uid_lock taken from inside
of process_notifier() will create contention which slows down process
exit. Defer stats accounting in such case to avoid lock contention.
