[PATCH] config: Fix CONFIG_LFS option

[Trond Myklebust <Trond.Myklebust@netapp.com>]

The help text says that if you select CONFIG_LBD, then it will
automatically select CONFIG_LFS. Nope... That isn't currently the
case.

 - Fix CONFIG_LBD to automatically select CONFIG_LFS
 - Get rid of the cruft in the help text mentioning CONFIG_LBD
 - Tell unsure users to select CONFIG_LFS.
