irdma(4): use related vnet for searching netdev

[bartosz.sobczak_intel.com]

Summary

It was found through testing that when ULP uses individual vnet, the search for the correct vlan_id may failing because of no proper interface with given address.

The solution is to use vnet associated to the connection whenever possible.

ip6_ifp_find() is independent of VIMAGE. It can take "vnet" as input parameter unconditionally.

Would it be simplified if vnet is declared with the default value "&init_net"?

I was preparing to push this yesterday, but I forgot to do the last step; I think @anzhu_netapp.com has a good point here because it'll reduce the number of VIMAGE blocks, but I probably would still push it and would just wait for a fix later.

Yeah, i agree, we can do that arrangement. I'll prepare subsequent change as soon as possible, in the meantime i think it could go in as it is.

Yep, cosmetic issue can be addressed separately.
