Drivers: hv: vmbus: Return -EINVAL for the sys files for unopened channels
commit fc96df16a1ce80cbb3c316ab7d4dc8cd5c2852ce upstream.
Before 98f4c651762c, we returned zeros for unopened channels.
With 98f4c651762c, we started to return random on-stack values.
We'd better return -EINVAL instead.
Fixes: 98f4c651762c ("hv: move ringbuffer bus attributes to dev_groups")
