cleanup for ramdisk failed to umount TMP_BUILD_DIR with device or resource busy error. The patch unmounts all the mountpoints under TMP_BUILD_DIR and detaches loop devices associated with TMP_IMAGE_PATH. The unmounts are applied with both force(-f) and lazy(-l) options. Force option is only for NFS mounts, it's kept here since no harm for lazy option. Change-Id: I84035e6a003d8135186b2fda3facbd2c37967529
