[PATCH v3] drm: Reduce scope of 'state' variable

[PATCH v3] drm: Reduce scope of 'state' variable

[Dawid Kurek]

Smaller scope reduces visibility of variable and makes usage of
uninitialized variable less possible.

Changes in v2:
	- separate declaration and initialization
Changes in v3:
	- add missing signed-off-by tag
