Raphael Norwitz 4fafedc9da libvhost-user: handle removal of identical regions ... Today if QEMU (or any other VMM) has sent multiple copies of the same region to a libvhost-user based backend and then attempts to remove the region, only one instance of the region will be removed, leaving stale copies of the region in dev->regions[]. This change resolves this by having vu_rem_mem_reg() iterate through all regions in dev->regions[] and delete all matching regions.
