This commit changes virtio/vsock to use sk_buff instead of
virtio_vsock_pkt. Beyond better conforming to other net code, using
sk_buff allows vsock to use sk_buff-dependent features in the future
(such as sockmap) and improves throughput.
This patch introduces the following performance changes:
Tool: Uperf
Env: Phys Host + L1 Guest
Payload: 64k
Threads: 16
Test Runs: 10
Type: SOCK_STREAM
Before: commit b7bfaa761d760 ("Linux 6.2-rc3")
Before

g2h: 16.77Gb/s
h2g: 10.56Gb/s

g2h: 21.04Gb/s
h2g: 10.76Gb/s

Changes in v10:
- vhost/vsock: use virtio_vsock_skb_dequeue()
- vhost/vsock: remove extra iov_length() call
- vhost/vsock: also consider hdr when evaluating that incoming size is
valid
- new uperf data
Tests seem fine!
