Commit 009f766 intended to filter multicast/broadcast, however
the NDIS filter wasn't set properly in non-promiscuous modes,
which resulted in issues like DHCP timeouts.
This patch sets the filter flags correctly.

Fixes: 009f766 ("hv_netvsc: filter multicast/broadcast")

   At least 12 digits needed here, and the summary line too, just like you do
