vhost/scsi: Add ANY_LAYOUT iov -> sgl mapping prerequisites
This patch adds ANY_LAYOUT prerequisites logic for accepting a set of
protection + data payloads via iov_iter. Also includes helpers for
calcuating SGLs + invoking vhost_scsi_map_to_sgl() with a known number
of iovecs.
Required by ANY_LAYOUT processing when struct iovec may be offset into
the first outgoing virtio-scsi request header.
