Subject: [PATCH] media/gpu/vaapi: Relax the version check for VA-API

Since the newer versions of VA-API are ABI compatible, relax the
version checks for VA-API, by using VA_CHECK_VERSION().
This will help in updating the libva to the latest releases,
while still supporting the old versions, till the new version of
libva is merged and picked by the builds. Thus ensuring that
hardware accleration is not broken while updating the libva.

Bug: 905814
TEST=libva-2.3.0 and libva-2.1.0 are able to do hardware acceleration.
