virtio-fs: fix MSI-X nvectors calculation
The following MSI-X vectors are required: * VIRTIO Configuration Change * hiprio virtqueue * requests virtqueues Fix the calculation to reserve enough MSI-X vectors. Otherwise guest drivers fall back to a sub-optional configuration where all virtqueues share a single vector. This change does not break live migration compatibility since vhost-user-fs-pci devices are not migratable yet.
