vhost-user-blk: Get more feature flags from vhost device 

VIRTIO_F_RING_PACKED and VIRTIO_F_IOMMU_PLATFORM need to be supported by
the vhost device, otherwise advertising it to the guest doesn't result
in a working configuration. They are currently not supported by the
vhost-user-blk export in QEMU.
