Revert "drm/radeon: remove drm_vblank_get|put from pflip handling"

This reverts commit 75f36d861957cb05b7889af24c8cd4a789398304.

drm_vblank_get() is necessary to ensure the DRM vblank counter value is
up to date in drm_send_vblank_event().

Seems to fix weston hangs waiting for page flips to complete.
