prevent softlock up when VTi domain destruction by making relinquish_memory() continuable. It was assumed that mm_teardown() frees most of page_list so that the list which is passed to relinquish_memory() is short. However the assumption isn't true for VTi domain case because qemu-dm maps all the domain pages. To avoid softlock up message, make relinquish_memory() continuable. -- yamahata
