libext2fs: fix rb_resize_bmap to handle the padding bits

The bits between end and real_end are set as a safety measure for the
kernel when it uses the bit scan instructions.  We need to take this
into account when shrinking or growing the block allocation bitmap,
before we can safely use rbtree bitmaps in resize2fs.
