drm/i915: Fix infinite loop regression from 21dd3734
By returning EAGAIN upon a wedged GPU before attempting to wait, we
would hit an infinite loop of repeating operation without ever
progressing. Instead this needs to be EIO so that userspace knows that
the GPU is truly wedged and not in the process of error recovery.
Similarly, we need to handle the error recovery during i915_gem_fault.
