Fix committed, commit http://kernel.ubuntu.com/git/ubuntu/autotest-
client-tests.git/commit/?id=9aba531dcecbd1505ac9bac3736f2124af942d34
This makes the server export detection more robust, tested on xenial,
bionic, cosmic and disco, amd64/i386/ppc64el. Hopefully this will
address all weird mount failures.

Title:
ubuntu_nbd_smoke_test failed when running with the smoke test suite on
X 4.4 s390x zVM
Status in ubuntu-kernel-tests:
Fix Committed
Status in linux package in Ubuntu:
Confirmed
Bug description:
This test can pass if you run it manually on s390x zVM.
But it will fail when you try to run it with the smoke test suite on
jenkins.
And this issue was only spotted on this s390x zVM (kernel01)
