Subject: [PATCH] vsock/virtio: remove unused 'work' field from 'struct virtio_vsock_pkt'

The 'work' field was introduced with commit 06a8fc78367d0
("VSOCK: Introduce virtio_vsock_common.ko")
but it is never used in the code, so we can remove it to save
memory allocated in the per-packet 'struct virtio_vsock_pkt'
