[PATCH][next] drm/i915: remove redundant assignment to variable test_result

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

The variable test_result is being initialized with a value that is
never read and it is being updated later with a new value.  The
initialization is redundant and can be removed.

Addresses-Coverity: ("Unused value")
