scsi: Remove CONFIG_SCSI_MULTI_LUN
Obsolete; either use 'max_lun' if the host supports only a limited number of LUNs or BLIST_NOLUN if the target has problems addressing more than one LUN. Signed-off-by: Hannes Reinecke <hare@suse.de> Reviewed-by: Ewan Milne <emilne@redhat.com> Signed-off-by: Christoph Hellwig <hch@lst.de>

- Some devices support more than one LUN (Logical Unit Number) in order
- to allow access to several media, e.g. CD jukebox, USB card reader,
- mobile phone in mass storage mode. This option forces the kernel to
- probe for all LUNs by default. This setting can be overridden by
- max_luns boot/module parameter. Note that this option does not affect
- devices conforming to SCSI-3 or higher as they can explicitly report
- their number of LUNs. It is safe to say Y here unless you have one of
- those rare devices which reacts in an unexpected way when probed for
- multiple LUNs.
