In commit "e2fsck: Let end_blk to be the maximum value of u32."
we fix a bug where a normal fallocate will cause e2fsck complain.
So add it to the regression test suite.

I've changed the description of this commit to reflect the change in
how I propose to fix the problem....

commit 8d12c46a22965179cae1e3b47778fdee5efeb513
Author: Tao Ma <boyu.mt@taobao.com>
Date:   Sun Jun 10 23:56:30 2012 -0400

    tests: add new test f_zero_extent_length
    
    If all of the extents in the last extent tree block (ETB) in a
    non-trivial extent tree contain uninitialized extents which are after
    the end of the file as defined by i_size, the hueristics will
    incorrectly estimate the last entry (and hence the node's e_len field)
    in the last entry of each level of the extent tree.
    
    As Tao Ma has noted, since e2fsck was requiring that the length
    (e_len) field of interior nodes be non-zero, this was causing false
    failures where e2fsck would declare that the extent tree was
    corrupted.
    
    This was fixed in commit 9c40d14841: "e2fsck: only check for
    zero-length leaf extents".  Add a regression test case to ensure that
    this issue remains fixed.
