RESEND: libata: check cdb len per dev instead of per host
Resending, with s/printk/DPRINTK/ as pointed out by Alan.
Fix libata to perform CDB len validation per device
rather than per host. This way, validation still works
when we have a mix of 12-byte and 16-byte devices on
a common host interface.
