i40e: Able to add up to 16 MAC filters on an untrusted VF

[ Upstream commit 06b6e2a2333eb3581567a7ac43ca465ef45f4daa ]

This patch fixes the problem with the driver being able to add only 7
multicast MAC address filters instead of 16. The problem is fixed by
changing the maximum number of MAC address filters to 16+1+1 (two extra
are needed because the driver uses 1 for unicast MAC address and 1 for
broadcast).
