[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.

201   - If you have a SCSI device that supports more than one LUN (Logical
202   - Unit Number), e.g. a CD jukebox, and only one LUN is detected, you
203   - can say Y here to force the SCSI driver to probe for multiple LUNs.
204   - A SCSI device with multiple LUNs acts logically like multiple SCSI
205   - devices. The vast majority of SCSI devices have only one LUN, and
206   - so most people can say N here. The max_luns boot/module parameter
207   - allows to override this setting.
  198 + Some devices support more than one LUN (Logical Unit Number) in order
  199 + to allow access to several media, e.g. CD jukebox, USB card reader,
  200 + mobile phone in mass storage mode. This option forces the kernel to
  201 + probe for all LUNs by default. This setting can be overriden by
  202 + max_luns boot/module parameter. Note that this option does not affect
  203 + devices conforming to SCSI-3 or higher as they can explicitely report
  204 + their number of LUNs. It is safe to say Y here unless you have one of
  205 + those rare devices which reacts in an unexpected way when probed for
  206 + multiple LUNs.
