immutable_object_cache: Endian fix for HeaderHelper

struct HeaderHelper is used to overlay buffer list data, which
was generated via encode, and therefore holds integer data in
fixed little-endian format.

Thus, HeaderHelper needs to use ceph_le32 instead of uint32_t
when accessing the len field.

Fixes (partially): https://tracker.ceph.com/issues/41605
