> HADOOP-6498 moved the calls.remove() call lower into the SUCCESS clause of receiveResponse(),
but didn't put a similar calls.remove into the ERROR clause. So, any RPC call that throws
an exception ends up orphaning the Call object in the connection's "calls" hashtable. This
prevents cleanup of the connection and is a memory leak for the call parameters.
