vfio: Get migration capability flags for container
Added helper functions to get IOMMU info capability chain.
Added function to get migration capability information from that
capability chain for IOMMU container.
Similar change was proposed earlier:
https://lists.gnu.org/archive/html/qemu-devel/2018-05/msg03759.html
Disable migration for devices if IOMMU module doesn't support migration
capability.
