drm/vblank: Fix -Wformat compile warnings on some arches

Browse Source 
On some architectures like ppc64le and aarch64, compiling with
-Wformat=1 will throw the following warnings:

  In file included from drivers/gpu/drm/drm_vblank.c:33:
  drivers/gpu/drm/drm_vblank.c: In function 'drm_update_vblank_count':
  drivers/gpu/drm/drm_vblank.c:273:16: warning: format '%llu' expects
  argument of type 'long long unsigned int', but argument 4 has type
  'long int' [-Wformat=]

                  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  ./include/drm/drm_print.h:407:22: note: in definition of macro
  'DRM_DEBUG_VBL'
    drm_dbg(DRM_UT_VBL, fmt, ##__VA_ARGS__)

  drivers/gpu/drm/drm_vblank.c:274:22: note: format string is defined here

                     ~~~^
                     %lu

So, fix that with a typecast.
