libavfilter/vf_vpp_qsv: Fix a timestamp bug when framerate is not set
If user doesn't set framerate when he creates a filter, the filter uses
default framerate {0, 1}. This causes error when setting timebase to
1/framerate. Now change it to pass inlink->time_base to outlink when
framerate is not set.
This patch fixes ticket: #10476 #10468
