This is unfortunately not a complete solution. If we want to add
parameter(s) to tst_acquire_device() to specify minimal (and possibly
maximal) device size we have to check the $LTP_DEV device size and fall
back to loopback device if it's not in between the bounds, otherwise the
test will still fail if smaller than requested device was created in
runltp (which is the case at the moment).
