i40evf: handle many MAC filters correctly
When a lot (many hundreds) of MAC or VLAN filters are added at one time, we can overflow the Admin Queue buffer size with all the requests. Unfortunately, the driver would then calculate the message size incorrectly, causing it to be rejected by the PF. Furthermore, there was no mechanism to trigger another request to allow for configuring the rest of the filters that didn't fit into the first request. To fix this, recalculate the correct buffer size when we detect the overflow condition instead of just assuming the max buffer size. Also, don't clear the request bit in adapter->aq_required when we have an overflow, so that the rest of the filters can be processed later.
