ext4: fix potential htree corruption when growing large_dir directories
Commit b5776e7524af ("ext4: fix potential htree index checksum corruption) removed a required restart when multiple levels of index nodes need to be split. Fix this to avoid directory htree corruptions when using the large_dir feature.
