Commit 8b83dad82512a6948b63408f964463b063ad24c9 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.

    avfilter/vpp_qsv: fix regression on older api versions (e.g. 1.11)
    
    Fix a recently introduced regression when using QSV VPP.
    
    v2: Fixed commit message wrapping v3: Use different way to acquire
    runtime version

Thanks for the new patch version, it works well for me.

It would be better to change the return type of get_mfx_version from int to
mfxStatus if returning MFXQueryVersion(device_hwctx->session, mfx_version) here.
Otherwise map the returned mfx status to ffmpeg status, then return ffmpeg
status.
