LockWeak<T> allows to create data race to T.

In the affected versions of this crate, LockWeak<T> unconditionally implemented Send with no trait bounds on T. LockWeak<T> doesn't own T and only provides &T.

This allows concurrent access to a non-Sync T, which can cause undefined behavior like data races.
