Merge patch series "libsas: Some tidy-up"

John Garry <john.g.garry@oracle.com> says:

This series tidies-up libsas a bit, including:
- delete structure(s) with only one member
- delete structure members which are only ever set
- delete structure members which are never set and code which relies on
  that member being set

This conflicts with the following series:
https://lore.kernel.org/linux-scsi/20230809132249.37948-1-yuehaibing@huawei.com/

Any conflict should be trivial to resolve.

Based on mkp-scsi staging at a18e81d17a7e ("scsi: ufs: ufs-pci: Add support for QEMU")
