Cherry-pick from https://gerrit.onos.onlab.us/#/c/336/

Fix a bug when deleting all flows. (ONOS-981)

Conflicts:

	src/main/java/net/onrc/onos/ofcontroller/flowmanager/FlowDatabaseOperation.java

NOTE: The above conflict has been resolved by hand.
Also, the code related to the Titan-specific exception has been removed,
because it doesn't apply anymore.
