Hmm, we may want to add this into test.sh because otherwise we will need
to carry this snippet of code in each testcase that works with loop
devices.
Would calling umount without -d and detach_device() (from tst_device.c
via apicmd) help here? (it seems to fix the very same problem, it this
function does not work, it needs to be fixed anyway)
