drm/i915/guc: Fix Gen9 GuC loading workarounds

Browse source

In commit 4502e9ec82 ("drm/i915/uc: Unify firmware loading") we
stopped converting errors detected during firmware transfer into
-EAGAIN and this indirectly killed our workarounds for Gen9 GuC.
Reactivate those workarounds by looking for actual -ETIMEDOUT error.
