drm/i915/guc: Fix request re-submission after reset
In order to ensure no missed interrupts we must first re-direct
the interrupts to GuC, and only then re-submit the requests to
be replayed after a GPU reset. Otherwise context switch can fire
before GuC has been set up to receive it triggering more hangs.
v2: Rebase.
