ext4: fix potential htree corruption when growing large_dir directories
commit 877ba3f729fd3d8ef0e29bc2a55e57cfa54b2e43 upstream.
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.
