vmci: type promotion bug in qp_host_get_user_memory()
[ Upstream commit 7fb2fd4e25fc1fb10dcb30b5519de257cfeae84c ]
The problem is that if get_user_pages_fast() fails and returns a
negative error code, it gets type promoted to a high positive value and
treated as a success.
Fixes: 06164d2b72aa ("VMCI: queue pairs implementation.")
