Subject: [PATCH][next] drm/i915/selftests: fix memory leak of 'spin'

From: Colin Ian King <colin.king@...onical.com>

There is a memory leak of 'spin' on an error return path. Fix this by
kfree'ing spin before the return.

Fixes: c06ee6ff2cbc ("drm/i915/selftests: Context SSEU reconfiguration tests")
