[PATCH] xf86-video-ati/DRI2: fix high-crtc/vblank oversight/bug introduced in f0b7d7b449cc77bb2b281d81108507f8bc2e6018

[Ilija Hadzic]

improvements to high-crtc handling done in
f0b7d7b449cc77bb2b281d81108507f8bc2e6018 introduced a bug that caused
the populate_vbl_request_type to never use the high-crtc field even
when it should. The reason is that the offending patch put the code
under #ifdef DRM_VBLANK_HIGH_CRTC_MASK which is not visible outside the
enum type, so #else was always taken in compilation type. This patch
fixes it by basing #ifdef on (pre-processor visible)
DRM_VBLANK_HIGH_CRTC_SHIFT constant
