[SCSI] Update wording of CONFIG_SCSI_MULTI_LUN help 



I had to set CONFIG_SCSI_MULTI_LUN to y in order to get my SE W595
working when plugging it as a mass storage. Looking at SCSI option to
get a phone behaving correctly was convoluted to say the least. There
are quite a few other reports about USB card readers needing this option
as well. This patch improves the help text to make the use of the option
more obvious.

	  If you have a SCSI device that supports more than one LUN (Logical

	  Unit Number), e.g. a CD jukebox, and only one LUN is detected, you

	  can say Y here to force the SCSI driver to probe for multiple LUNs.

	  A SCSI device with multiple LUNs acts logically like multiple SCSI

	  devices. The vast majority of SCSI devices have only one LUN, and

	  so most people can say N here. The max_luns boot/module parameter 

	  allows to override this setting.

	  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 overriden by

	  max_luns boot/module parameter. Note that this option does not affect

	  devices conforming to SCSI-3 or higher as they can explicitely 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.
