hv/netvsc: fix handling of fallback to single queue mode 



[ Upstream commit 916c5e1413be058d1c1f6e502db350df890730ce ]

The netvsc device may need to fallback to running in single queue
mode if host side only wants to support single queue.

Recent change for handling mtu broke this in setup logic.
