Fix NPE while performing NetworkStatsService.removeUidsLocked()
Symptom:
NPE occurred while performing NetworkStatsService.removeUidsLocked().
Root cause:
NetworkStatsService refers to mUidRecorder at
NetworkStatsService.removeUidsLocked() when mUserReceiver received
Intent.ACTION_USER_REMOVED.
However NetworkStatsService sets mUidRecorder to null without
unregistering mUserReceiver when mShutdownReceiver received
Intent.ACTION_SHUTDOWN.
Therefore NPE occurred when mUserReceiver received
Intent.ACTION_USER_REMOVED after mShutdownReceiver received
Intent.ACTION_SHUTDOWN.
Solution:
Unregister mUserReceiver before setting mUidRecorder to null when
mShutdownReceiver received Intent.ACTION_SHUTDOWN.
