ofproto-dpif-upcall: Make miss handlers accumulate coverage counters.

The miss handler threads do not call poll_block(), which calls
coverage_clear() indirectly.  This meant that coverage counters incremented
by miss handler threads never got integrated into the global coverage
counters and therefore did not show up in coverage logging or
"ovs-appctl coverage/show" output.  This commit fixes the problem.
