callQueueLen directly in HBaseServer".

  Haven't figured out why there were extra failed tests reported by Hadoop QA for patch v2.
  On my MacBook, the following tests passed (last command looped TestAtomicOperation 4 times):
    558  mt -Dtest=TestAtomicOperation
    559  mt -Dtest=TestLruBlockCache
    561  ~/runtest.sh 4 TestAtomicOperation

> It's better to directly update the metrics outside HBaseRpcMetrics so that HBaseRpcMetrics
doesn't have to hold reference to HBaseServer.
