Dmitry Baryshkov 52feb58f9b misc: fastrpc: restrict user apps from sending kernel RPC messages 
commit 20c40794eb85ea29852d7bc37c55713802a543d6 upstream.

Verify that user applications are not using the kernel RPC message
handle to restrict them from directly attaching to guest OS on the
remote subsystem. This is a port of CVE-2019-2308 fix.
