[PATCH] iotests/108: avoid leaking FUSE mount

[PATCH] iotests/108: avoid leaking FUSE mount

[Stefan Hajnoczi]

The QEMU s390x CI gitlab-runner recently broke because qemu-iotests 108
FUSE mount leaked and prevented the setup of the gitlab-runner
environment:

  chmod: cannot access '/home/gitlab-runner/builds/P3MFS4LUf/0/qemu-project/qemu/build/scratch/qcow2-file-108/fuse-export': Transport endpoint is not connected

https://gitlab.com/qemu-project/qemu/-/jobs/14796143507#L11

Always umount the FUSE export when cleaning up to prevent the leak.

Closes: https://gitlab.com/qemu-project/qemu/-/work_items/3541
