i40e: add interrupt rate limit verbosity

Due to the resolution of the register controlling interrupt rate limiting, setting certain values for the interrupt rate limit make it appear as though the limiting is not completely accurate. The problem is that the interrupt rate limit is getting rounded down to the nearest multiple of 4. This patch fixes the problem by adding some feedback to the user as to the actual interrupt rate limit being used when it differs from the requested limit. Without this patch setting interrupt rate limits may appear to behave inaccurately.
