This patch was to fix a reported Hangouts deadlock/freezing issue in VP8 encoder(issue 27232610). The original encoder loopfilter synchronization happened in the following frame, which was prone to causing problems in some complex use cases. This patch simplified the synchronization logic. More testing needs to be done. Change-Id: I38fd3f35d11f98fae1e44546aa5e4c6d6e19c4be
