What else is required to complete the ANY_LAYOUT conversion..?
Basically, you need to stop expecting the request and response headers
to be in a separate iov, and also vhost-scsi should not expect pi to be
in a separate iov than the main data. A layout that has everything in
the same iov would be fine, and similarly for a layout that has the CDB
in a separate iov than the rest of the header.
