avfilter: update filter timeline state only on main link

Browse Source 
At present, consume_update evaluates timeline state on all links for
a multi-input filter. This can lead to the filter being incorrectly
en/dis-abled when evaluation on a frame on a secondary link leads to
a different result than the frame on the current main link next in
line for processing.
