vainfo invalid VAContextID

[uartie]

vainfo is provided by https://github.com/01org/libva-utils and is the defacto tool used by developers and users to run a sanity check on vaapi driver capabilities. Unfortunately, vainfo fails when using iHD vaapi driver:

$ export LIBVA_DRIVER_NAME=iHD
$ vainfo
libva info: VA-API version 1.0.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'iHD'
libva info: Trying to open /home/uaeoff/Work/workspace/media/install/lib/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_0
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.0 (libva 2.0.1.pre1)
vainfo: Driver version: 2.0.0
vainfo: Supported profile and entrypoints
vaQueryConfigProfiles failed with error code 5 (invalid VAContextID),exit

Sorry, this was observed on an unsupported platform (HSW). vainfo works fine on SKL
