[Stable-8.2.1 15/38] hw/vfio: fix iteration over global VFIODevice list

[Michael Tokarev]

From: Volker Rümelin <vr_qemu@t-online.de>

Commit 3d779abafe ("vfio/common: Introduce a global VFIODevice list")
introduced a global VFIODevice list, but forgot to update the list
element field name when iterating over the new list. Change the code
to use the correct list element field.
