ofproto-dpif-upcall: Transition ukey on dp_ops error.

In most situations, we don't expect that a flow we've successfully
dumped, which we intend to delete, cannot be deleted. However, to make
this code more resilient to ensure that ukeys *will* transition in all
cases (including an error at this stage), grab the lock and transition
this ukey forward to the evicted state, effectively treating a failure
to delete as "this flow is already gone".

If we subsequently find out that it wasn't deleted, then that's ok - we
will re-dump, and validate at that stage, which should lead to creating
a new ukey or deleting the datapath flow when that happens.
