e2fsck: fix sparse bmap to extent conversion

When e2fsck is trying to convert a sparse block-mapped file to an extent
file, we incorrectly merge block mappings that are physically contiguous
but not logically contiguous because of insufficient checking with the
extent we're constructing.  Therefore, compare the logical offsets for
contiguity as well.
