[SCSI] aacraid: READ_CAPACITY_16 shouldn't trust allocation length in cdb
When aacraid spoofs READ_CAPACITY_16, it assumes that the data length in the sg list is equal to allocation length in cdb. But sg can put any value in scb so the driver needs to check both the data length in the sg list and allocation length in cdb. If allocation length is larger than the response length that the driver expects, it clears the data buffer in the sg list to zero but it doesn't need to do. Just setting resid is fine.
