[PATCH 4/5] drm/i915: remove unused variables from ironlake_crtc_mode_set

[Paulo Zanoni <przanoni@gmail.com>]

From: Paulo Zanoni <paulo.r.zanoni@intel.com>

The last patches moved a lot of code from ironlake_crtc_mode_set to
sub-functions, so these variables became useless. You could get
warnings by enabling -Wunused-but-set-variable.
