  dpif-netdev: Increase the number of EMC entries

Prior to this commit, the number of possible entries in the Exact
Match Cache stood at 1024 per thread exacting to 0.18Mb. A typical
server system will have 2.5Mb cache per core meaning a larger EMC will
comfortably fit in. This patch increases the number of entries to 8192
per thread (1.4Mb) which in turn yields improved throughput when
processing multiple flows of traffic.
