svm: asan: fix asan support
- restrict the unittests SVM address space to what is supported by ASan - mark SVM mmap()ed address space accessible for ASan - SVM shared memory heap scheme means some allocation can happen outside the current process. Lazily mark those accessible for ASan Type: fix Change-Id: I7c196c80b2a5297651d0afa54f1a8e478fcf59b1 Signed-off-by: Benoît Ganne <bganne@cisco.com>
