staging/lustre/llite: get rid of unused ll_super_blocks list
ll_super_blocks became unused quite a while ago with switch to the new CLIO code. So this patch removes the list, ll_sb_lock spinlock that guards it and superblock info ll_list linkage. Signed-off-by: Oleg Drokin <green@linuxhacker.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
