drm/i915: call drm_handle_vblank before finish_page_flip

commit 74d44445afb9f50126eba052adeb89827cee88f3 upstream.

... since finish_page_flip needs the vblank timestamp generated
in drm_handle_vblank. Somehow all the gmch platforms get it right,
but all the pch platform irq handlers get is wrong. Hooray for copy&
pasting!

Currently this gets papered over by a gross hack in finish_page_flip.
A second patch will remove that.

Note that without this, the new timestamp sanity checks in flip_test
occasionally get tripped up, hence the cc: stable tag.

[bwh: Backported to 3.2: no loop over pipes in ivybridge_irq_handler(),
 so make a similar change to that in ironlake_irq_handler()]
