util/vfio-helpers.c: Use ram_block_discard_disable() in qemu_vfio_open_pci() Currently, when using "nvme://" for a block device, like
-drive file=nvme://0000:01:00.0/1,if=none,id=drive0 \
-device virtio-blk,drive=drive0 \
VFIO may pin all guest memory, and discarding of RAM no longer works as
expected. I was able to reproduce this easily with my
01:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd
NVMe SSD Controller SM981/PM981/PM983
Similar to common VFIO, we have to disable it, making sure that:
a) virtio-balloon won't discard any memory ("silently disabled")
b) virtio-mem and nvme:// run mutually exclusive
