[PATCH v2] drm/i915: Fix "mitigations" parsing if i915 is builtin

I met below error during boot with i915 builtin if pass "i915.mitigations=off": [0.015589] Booting kernel: `off' invalid for parameter `i915.mitigations' The reason is slab subsystem isn't ready at that time, so kstrdup() returns NULL. Fix this issue by using stack var instead of kstrdup().
