drm: unbreak VA_DRM_IsRenderNodeFd on FreeBSD

[jbeich]

drmGetDeviceNameFromFd doesn't support render nodes according to libdrm@37d790f. And st_rdev & 0x80 may not work on FreeBSD because major/minor semantics are different.

LGTM

[XinfengZhang]

the only concern is: the commit of the libdrm is after 2.4, maybe will cant compile with 2.4, such as 2.4.53 ...

[XinfengZhang]

@jbeich , please help to check whether it work with older version libdrm. in libva configure, it only require the version > 2.4

[jbeich]

@XinfengZhang, this PR fails with libdrm < 2.4.74 but even unmodified libva requires drmGetDeviceNameFromFd which was added in libdrm >= 2.4.16. However, downstream with old libdrm package usually also have old libva.

As I've removed my fork (to avoid clutter) a fix would require a separate PR e.g.,

Can this be finalized and merged?

[rcombs]

Oh, I see this is replaced by #491. Can this be closed out, then?

[evelikov]

Fwiw I've removed the function all together, in favour of drmGetNodeTypeFromFd() with #614

[dvrogozh]

This part was reworked with recently merged #614. Please, take a look and reopen/submit new PR if needed.
