testscripts/test_fs_bind.sh: Unmount ${sandbox} when do_break=1 in run_test()
If we run the original test_fs_bind.sh repeatedly: In the first cycle
we have no problems; but in the second cycle save_sandbox() will return
with "stale catalog..." and do_break is set to 1, then run_test() will
return without unmounting ${sandbox}. And at the end, remove ${sandbox}
fails with "rm: cannot remove ‘/tmp/ltp-XXXXXXXXXX/sandbox’: Device or
resource busy". I think this is the correct way to fix this issue:
