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.

	  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.
