Dexuan Cui dac7314127 Drivers: hv: vmbus: Return -EINVAL for the sys files for unopened channels 
commit fc96df16a1 upstream.

Before 98f4c65176, we returned zeros for unopened channels.
With 98f4c65176, we started to return random on-stack values.

We'd better return -EINVAL instead.

Fixes: 98f4c65176 ("hv: move ringbuffer bus attributes to dev_groups")
