A replacement patch that works in both cases

a6decb91ac2c035c381d59f1f1fabfeb2f869f95 causes a deadlock (1) in one
particular test case. It was made to avoid a deadlock in another case (2)

I originally had a different patch to fix (2), and it happens to also work with
(1). The current patch was done after discussing with wtay on IRC (no logs).

(1)
Using playbin on a local http server to a file with raw video in matroska

(2)
Using buffering, the pipeline is set to PAUSED, and then to PLAYING upon
receiving a 100% buffering message. A deadlock happens *not always* after a
couple buffering messages with small percentages.
