i40e: Use even more ARQ descriptors



When enabling 64 VFs and loading the VF driver in the host kernel, we
can easily overrun the PF's admin receive queue. Double the size of this
queue, and increase the work limit to allow the PF to handle more
requests in a single pass through the service task.
