videoscale: Fix assertion on caps fixation

When fixating caps, from_par should always be initialized
with a fixed value.

In case the fixation is from src to sink pad it was setting
the from par (srcpad par) to a fraction range, this patch initializes
it to 1/1, based on the assumption that missing PAR is 1/1.
