A regression was introduced in PR #62174 that added a `ceph_assert()` statement which incorrectly assumes alloc_unit is always aligned. This causes OSD crashes when the assertion fails.
This cherry-pick removes the faulty assertion, resolving the crash while maintaining correct functionality for both aligned and unaligned alloc_unit values.
