Commit 8b83dad82512a6948b63408f964463b063ad24c9 introduced a regression in a way
that scaling via vpp_qsv didn'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.
