softworkz 479f3c6598 avfilter/vpp_qsv: fix regression on older api versions (e.g. 1.11) 
Commit 8b83dad825 introduced a
regression in a way that scaling via vpp_qsv doesn't work any longer
for devices with an MSDK runtime version lower than 1.19. This is true
for older CPUs which are stuck at 1.11.
The commit added checks for the compile-sdk version but it didn't test
for the runtime version.
