• lavu/hwcontext_qsv : use mfxImplDescription instead of mfxExtendedDeviceId on Linux

  lavu/hwcontext_qsv : use mfxImplDescription instead of mfxExtendedDeviceId on Linux
  mfxExtendedDeviceId mightn't be supported in certain configurations of
  
  oneVPL on Linux, so we can't ensure a property filter for
  
  mfxExtendedDeviceId.DeviceID or mfxExtendedDeviceId.VendorID works as
  
  expected. This fixed the issue mentioned in [1]
