misc: asan: do not poison memory after munmap()
It is a bad idea to poison memory after munmap because the address space can be reused (eg. for global data of dlopen()ed object) and ASan model allows access by default. Moreover, access to a stale address space will fault. Type: fix Change-Id: I356de422f255447d9d50a3a71fb0c2eaa790d731 Signed-off-by: Benoît Ganne <bganne@cisco.com>
