Subject: hv_netvsc: hide warnings about uninitialized/missing rndis device
Git-commit: b5eb819dcbcbeca7a047573a5218cb8f703709c9
References: fate#323887

Hyper-V hosts are known to send RNDIS messages even after we halt the
device in rndis_filter_halt_device(). Remove user visible messages
as they are not really useful.
