[PATCH net-next] hv_netvsc: Correct filter setting for multicast/broadcast

[Mohammed Gamal]

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")
