vhost-scsi: Allocate T10 PI structs only when enabled
T10 PI is not a widely used feature. This has us only allocate the
structs for it if the feature has been enabled. For a common small setup
where you have 1 virtqueue and 128 commands per queue, this saves:
8MB = 32 bytes per sg * 2048 entries * 128 commands
per vhost-scsi device.
