iovec: move memcpy_from/toiovecend to lib/iovec.c
ERROR: "memcpy_fromiovecend" [drivers/vhost/vhost_scsi.ko] undefined!
commit 9f977ef7b671f6169eca78bf40f230fe84b7c7e5
vhost-scsi: Include prot_bytes into expected data transfer length
in target-pending makes drivers/vhost/scsi.c call memcpy_fromiovecend().
This function is not available when CONFIG_NET is not enabled.
socket.h already includes uio.h, so no callers need updating.
