[SPARK-3154][STREAMING] Replace ConcurrentHashMap with mutable.HashMap and
remove @volatile from 'stopped'
Since `sequenceNumberToProcessor` and `stopped` are both protected by the
lock `sequenceNumberToProcessor`, `ConcurrentHashMap` and `volatile` is
unnecessary. So this PR updated them accordingly.
