Stephen Hemminger 6712cc9c22 vmbus: don't return values for uninitalized channels ...

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")
