Subject: [PATCH v4 2/2] rust: sync: Make Guard::new() public

Since we added a Lock::from_raw() function previously, it makes sense to
also introduce an interface for creating a Guard from a reference to a Lock
for instances where we've derived the Lock from a raw pointer and know that
the lock is already acquired, something we do in the KMS API.
