In Linux 0.99.12, a table of the command size for different CDB group
codes was added with a value of 10 for groups 6 and 7. In the SCSI
specification it is specified that for groups 6 and 7, the length of
the CDB is vendor-specific.

This fixes an issue when sending a CDB of size 6 with a group code of 6
or 7, where libata will respond with DID_ERROR instead of sending the
command because the length is below the value of 10 found in this table.
