drm/kms/radeon: Reorder vblank and pageflip interrupt handling.
In the vblank irq handler, calls to actual vblank handling,
or at least drm_handle_vblank(), need to happen before
calls to radeon_crtc_handle_flip().
Reason: The high precision pageflip timestamping
and some other pageflip optimizations will need the updated
vblank count and timestamps for the current vblank interval.
These are calculated in drm_handle_vblank(), therefore it
must go first.
