[Bug 1324659] [NEW] dump_flows_for_table() needs to handle run_ofctl failing

 

Public bug reported:

The function dump_flows_for_table() calls run_ofctl() to run the "dump-
flows" command. In the case of this occuring during an OVS restart,
run_ofctl() will fail, and an attempt to run splitlines() is made on a
None object.
