Dan Carpenter 37f43c12f5 vmci: type promotion bug in qp_host_get_user_memory() ...

[ Upstream commit 7fb2fd4e25 ]

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: 06164d2b72 ("VMCI: queue pairs implementation.")
