The fix posted exclusively changes the behavior of AHCI devices; however
the locking changes that jostled the AHCI bug loose could in theory
jostle loose some bugs in other devices, too.
I don't think it is possible that the fix for AHCI would have any impact
on virtio-scsi devices.
If you're seeing issues in virtio-scsi, I'd make a new writeup in a new LP.

Title:
Issue with qemu 2.12.0 + SATA
Status in QEMU:
Fix Committed
Bug description:
[EDIT: I first thought that OVMF was the issue, but it turns out to be
SATA]
I had a Windows 10 VM running perfectly fine with a SATA drive, since
I upgraded to qemu 2.12, the guests hangs for a couple of minutes,
works for a few seconds, and hangs again, etc. By "hang" I mean it
doesn't freeze, but it looks like it's waiting on IO or something, I
can move the mouse but everything needing disk access is unresponsive.
What doesn't work: qemu 2.12 with SATA
What works: using VirIO-SCSI with qemu 2.12 or downgrading qemu to 2.11.1 and
keep using SATA.
Platform is arch linux 4.16.7 on skylake and Haswell, I have attached
the vm xml file.
