[UNIATA] Better split of model name between Vendor and Product

Browse source 
UNIATA is converting IDE identify data into SCSI identify data.
However, IDE model is described with a unique field of 20 chars,
while SCSI model is described with 2 fields of 16 + 8 chars.
When displaying SCSI model, a space is added between vendor and product
fields.

Try to split model into vendor and product on a space if possible.
