scsi: Documentation/scsi: Remove nodisconnect parameter

The driver that used the 'nodisconnect' parameter was removed in commit
565bae6a ("[SCSI] 53c7xx: kill driver"). Related documentation was
cleaned up in commit f37a7238 ("[SCSI] 53c7xx: fix removal
fallout"), except for the remaining two mentions that are removed here.
