qemu: Mark NVMe disks as 'need VFIO'

There are couple of places where a domain with a VFIO device gets
special treatment: in CGroups when enabling/disabling access to
/dev/vfio/vfio, and when creating/removing nodes in domain mount
namespace. Well, a NVMe disk is a VFIO device too. Fortunately,
we have this qemuDomainNeedsVFIO() function which is the only
place that needs adjustment.
