Emulation of the block limits VPD page called back into scsi-disk.c, which however expected the request to be for a SCSIDiskState and accessed a scsi-generic device outside the bounds of its struct (namely to retrieve s->max_unmap_size and s->max_io_size). To avoid this, move the emulation code to a separate function that takes a new SCSIBlockLimits struct and marshals it into the VPD response format.
