ext4: fix indirect punch hole corruption
Fixes: 4f579ae7de560e5f449587a6c3f02594d53d4d51
This bug fixes several corner case bugs related to hole punching on EXT
file systems that use indirect mapping. One case was reproduced here,
and I've tested with this patch and it resolves the issue:

I've also been able to cherry-pick these cleanly into the aforementioned
trees and they build. I've only tested on 3.19. I believe Omar may have
additional test cases.
Thanks,
