hv_netvsc: Set VF priv_flags to IFF_NO_ADDRCONF before open to prevent IPv6 addrconf

Browse Source 
[ Upstream commit d7501e076d859d2f381d57bd984ff6db13172727 ]

Set an additional flag IFF_NO_ADDRCONF to prevent ipv6 addrconf.

Commit under Fixes added a new flag change that was not made
to hv_netvsc resulting in the VF being assinged an IPv6.

Fixes: 8a321cf7be ("net: add IFF_NO_ADDRCONF and use it in bonding to prevent ipv6 addrconf")
