Commit 24eca2dce0f8 ("scsi: sd: Introduce manage_shutdown device flag") introduced the manage_shutdown boolean field for the same structure. Together, these 2 commits increase the size of struct scsi_device by 8 bytes by using booleans instead of defining the manage_xxx fields as single bit flags, similarly to other flags of this structure. Avoid this unnecessary structure size increase and be consistent with the definition of other flags by reverting the definitions of the manage_xxx fields as single bit flags.
