Stephen Hemminger d5995b9a92 vmbus: don't return values for uninitalized channels ...

commit 6712cc9c22 upstream.

For unsupported device types, the vmbus channel ringbuffer is never
initialized, and therefore reading the sysfs files will return garbage
or cause a kernel OOPS.

Fixes: c2e5df616e ("vmbus: add per-channel sysfs info")
