[PATCH v3 6/7] initramfs: Use mutable list iterator

[Kaitao Cheng <kaitao.cheng@linux.dev>]

From: Kaitao Cheng <chengkaitao@kylinos.cn>

The safe list iterator in dir_utime() requires a temporary cursor even
though the loop body only deletes and frees the current entry.  The
mutable iterator keeps the same removal-safe traversal semantics while
hiding the internal cursor from the call site.

Switch dir_utime() to list_for_each_entry_mutable() and drop the unused
temporary cursor variable.  No functional change is intended.
