vsock/virtio: Allocate nonlinear SKBs for handling large transmit buffers (2025-08-01 09:11:09 -0400)

Changes from v1: drop commits that I put in there by mistake. Sorry!

---------------------------------------------------------------- virtio, vhost: features, fixes

vhost can now support legacy threading if enabled in Kconfig vsock memory allocation strategies for large buffers have been improved, reducing pressure on kmalloc vhost now supports the in-order feature guest bits missed the merge window

fixes, cleanups all over the place
