[PATCH] drm: compat: Fix compilation breakage due to drm_vblank_wait rename

[Laurent Pinchart]

The drm_vblank_wait() function was renamed to drm_vblank_wait_ioctl() in
the DRM tree in commit b6dcaaac4474 ("drm/vblank: _ioctl posfix for
ioctl handler"), while the DRM compat code was changed independently in
commit d5288c88c67c ("switch compat_drm_wait_vblank() to
drm_ioctl_kernel()") to call the old function.

Fix the resulting compilation breakage by calling the correct function.

Fixes: b6dcaaac4474 ("drm/vblank: _ioctl posfix for ioctl handler")
Fixes: d5288c88c67c ("switch compat_drm_wait_vblank() to drm_ioctl_kernel()")

Hello,

This patch fixes a compilation breakage waiting to happen when v4.13-rc1 will
be merged back in the drm-misc tree, as b6dcaaac4474 is in drm-misc-next and
d5288c88c67c in Linus' master branch.

I suppose that drm-misc-next is not an option, so we can apply this patch on
top of the merge, or squash it with the merge commit if we want to avoid
breaking bisection.
