ext4: Fix hueristic which avoids group preallocation for closed files

(cherry picked from commit 71780577306fd1e76c7a92e3b308db624d03adb9)

The hueristic was designed to avoid using locality group preallocation
when writing the last segment of a closed file.  Fix it by move
setting size to the maximum of size and isize until after we check
whether size == isize.
