scsi: add guest-recoverable ZBC errors

When running basic operations on zoned storage from the guest via
scsi-block, the following ASCs are reported for write or read commands
due to unexpected zone status or write pointer status:

     21h 04h: UNALIGNED WRITE COMMAND
     21h 05h: WRITE BOUNDARY VIOLATION
     21h 06h: ATTEMPT TO READ INVALID DATA
     55h 0Eh: INSUFFICIENT ZONE RESOURCES

Reporting these ASCs to the guest, the user applications can handle
them to manage zone/write pointer status, or help the user application
developers to understand the failure reason and fix bugs.
