[PATCH 5/5] drm/i915: check for errors on i915_drm_thaw

[Paulo Zanoni <przanoni@gmail.com>]

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

Before this patch, i915_drm_thaw would always return 0. After this
patch, it returns the error code from __i915_drm_thaw(), since it's
the only sub-function that can return an error code.
