ext4: iterate over buffer heads correctly in move_extent_per_page()
In commit bcff24887d00 ("ext4: don't read blocks from disk after extents
being swapped") bh is not updated correctly in the for loop and wrong
data has been written to disk. generic/324 catches this on sub-page
block size ext4.
Fixes: bcff24887d00 ("ext4: don't read blocks from disk after extentsbeing swapped")
