Nikolay Kuratov 067e6ec9f5 vsock/virtio: Fix unsigned integer wrap around in virtio_transport_has_space() 
[ Upstream commit 60316d7f10b17a7ebb1ead0642fee8710e1560e0 ]

We need to do signed arithmetic if we expect condition
`if (bytes < 0)` to be possible

Found by Linux Verification Center (linuxtesting.org) with SVACE
