[ Upstream commit 1f7698abedeeb3fef3cbcf78e16f925df675a179 ]
The current code assigns the reference, and then goes to increment
it if the toggle bit has changed. That way, we get
Toggle 0 0 0 0 1 1 1 1
ID 1 1 1 1 1 2 2 2
Fix that by assigning the post-toggle ID to get
Toggle 0 0 0 0 1 1 1 1
ID 1 1 1 1 2 2 2 2
