datapath: Simplify flow mask cache delete.
Currently on mask delete OVS moves last mask to the deleted place to keep flow cache consistent and compact for per cpu cache. But that generate duplicate entries in mask cache array which results in multiple flow lookups in case we miss flow cache. Following patch simply sets NULL for deleted entry.
