Subject: [PATCH] hyperv: rndis_filter needs to select NLS

rndis_filter uses utf8s_to_utf16s() which is provided by setting
NLS, so select NLS to fix the build error:

ERROR: modpost: "utf8s_to_utf16s" [drivers/net/hyperv/hv_netvsc.ko] undefined!

Fixes: 1ce09e899d28 ("hyperv: Add support for setting MAC from within guests")
