hv: vmbus: Constify struct kobj_type and struct attribute_group

Browse Source 
vmbus_chan_group  and vmbus_chan_type are not modified. They are only
used in the helpers which take a const type parameter.

Constifying these structures and moving them to a read-only section can
increase over all security.
