----------------------------------------

             Summary: Get rid of noop segment lock-unlock in PageMemoryImpl
                 Key: IGNITE-6719
                 URL: https://issues.apache.org/jira/browse/IGNITE-6719
             Project: Ignite
          Issue Type: Bug
      Security Level: Public (Viewable by anyone)
    Affects Versions: 2.3
            Reporter: Alexey Goncharuk
             Fix For: 2.4


We have the following pattern in PageMemoryImpl#stop():
{code}
volatile boolean closed;

...
closed = true;
writeLock.lock();
writeLock.unlock();
{code}

An empty lock/unlock pair can be eliminated, so the code must be changed and the flag should be moved to the segment class.
