qtdemux: don't assert if upstream size is not available when guessing bitrates

Browse source 
Fixes abort in push mode where the source is not seekable and the
size of the file is not available, as with

  cat foo.mp4 | gst-launch-1.0 playbin uri=fd://0

Less noticable with releases, since we disable all
g_assert() there.
