hv_sock: Initializing vsk->trans to NULL to prevent a dangling pointer
commit e629295bd60abf4da1db85b82819ca6a4f6c1e79 upstream.
When hvs is released, there is a possibility that vsk->trans may not
be initialized to NULL, which could lead to a dangling pointer.
This issue is resolved by initializing vsk->trans to NULL.
