drm/i915/guc: Skip communication warning on reset in progress

GuC IRQ and tasklet handler receive just single G2H message, and let other
messages to be received from next tasklet. During this chained tasklet
process, if reset process started, communication will be disabled.
Skip warning for this condition.
