Yes, that patch ended up in v4.9.9 [1]. Then some problems were reported, and 
it was reverted in v4.9.23 with commit 
0ee72d8f9b8e17b8e4ccfebc7a25cbc2d395cd6a [2].

I have just installed kernel version 4.11.6, from stretch-backports:

~$ uname -a
Linux alan 4.11.0-0.bpo.1-amd64 #1 SMP Debian 4.11.6-1~bpo9+1 (2017-07-09) 
x86_64 GNU/Linux

With that kernel hibernate seems to work, but I need further testing. I would 
suggest you to test that kernel version as well, and post your findings here.
