vp9: Reset buffer level on large bitrate changes.
For a large change in the target avg_frame_bandwidth, via the update in change_config()), reset the buffer_level to optimal_level. This fix prevents possible frame drops, where for example, encoder suddenly goes from lower to higher bitrate. Change-Id: I2f844c41d04c01240e85f574e59d2b9075c7eb6d
