KAFKA-6260: Ensure selection keys are removed from all collections on
socket close
When a socket is closed, we must remove corresponding selection keys from
internal collections. This fixes an NPE which is caused by attempting to access
the selection key's attached channel after it had been cleared after
disconnecting.
