scsi-disk: add SCSI_DISK_QUIRK_MODE_PAGE_VENDOR_SPECIFIC_APPLE quirk for Macintosh
Both MacOS and A/UX make use of vendor-specific MODE SELECT commands with PF=0 to identify SCSI devices: - MacOS sends a MODE SELECT command with PF=0 for the MODE_PAGE_VENDOR_SPECIFIC (0x0) mode page containing 2 bytes before initialising a disk - A/UX (installed on disk) sends a MODE SELECT command with PF=0 during SCSI bus enumeration, and gets stuck in an infinite loop if it fails Add a new SCSI_DISK_QUIRK_MODE_PAGE_VENDOR_SPECIFIC_APPLE quirk to allow both PF=0 MODE SELECT commands and implement a MODE_PAGE_VENDOR_SPECIFIC (0x0) mode page which is compatible with MacOS.
