qla2xxx: T10-Dif: add T10-PI support
Add support for T10-Dif for Target Mode to qla driver.
The driver will look for firmware attribute that support
this feature. When the feature is present, the capabilities
will be report to TCM layer.
Add CTIO CRC2 iocb to build T10-Dif commands.
Add support routines to process good & error cases.
