Commit 7f8f2757f3 ("bridge: Only store instant_stats on device changes")
introduced a race condition where instant stats would sometimes not be
updated to the database. In this case, monitor status reported by
'ovs-appctl bfd/show' would differ from 'ovs-vsctl list int'. This patch
fixes the issue by ensuring that the main thread waits on
connectivity_seqno in instant_stats_wait().Bug #22136.
