Alexandre Courbot e55b79102c devices: vhost: user: gpu: stop using Tube::try_clone() 
Stop using Tube::try_clone() as we want to remove this method.

This requires a change in how the GPU device tube is set. Cloning the
control tube on the VMM side allowed us to pass only one tube to the GPU
device, which received the first message asking for BAR information and
then immediately recycled its tube to send VmMemoryRequests.

Without cloning, we to create two full Tubes and pass the VmMemory tube
as part of the first message to the device. This is a bit more involved
but also safer.

BUG=b:222379833
BUG=b:221484449
TEST=`cargo run device gpu` replies to the initial message and receives
the tube from the VMM process.
