Subject: [PATCH 01/31] tune2fs: Don't convert block # to cluster # when
 clearing uninit_bg

When we're constructing the initial block bitmap as part of removing the
gdt_csum (i.e. uninit_bg) feature, we mustn't convert the block numbers to
cluster numbers because ext2fs_mark_block_bitmap2() does this for us.
