require quiesce for VFIO_USER_DIRTY_PAGES (#671)
If we require a quiesce for these calls, we can be sure that it will not race
with any usage of vfu_*_sg() calls, as a first step towards concurrency.
This is not ideal for VFIO_IOMMU_DIRTY_PAGES_FLAG_GET_BITMAP, which can
potentially be called multiple times during pre-copy phase, but that's something
we can fix later.
