Use AtomicInteger for lockIdGenerator in HRegion

                 Key: HBASE-2508
                 URL: https://issues.apache.org/jira/browse/HBASE-2508
             Project: Hadoop HBase
          Issue Type: Improvement
          Components: regionserver
    Affects Versions: 0.20.3
            Reporter: Ted Yu

Currently lockIdGenerator is an int. In obtainRowLock(), retry is needed in case of lockId

We can declare lockIdGenerator as AtomicInteger and use incrementAndGet() to get the next
lock Id.
