[LTP] [PATCH 1/1] tst_test.sh: Create (again) loop device in $TST_TMPDIR

[Petr Vorel]

Before 1f6bd6e66 loop device for testing test_dev.img was created in
shell API after cd to $TST_TMPDIR, therefore automatically removed
during the cleanup in _tst_do_exit(). This got broken in 1f6bd6e66,
fix it.

Although it'd be good not relying on this order (full path could be kept
and then pass to rm), it's better to have all LTP temporary files under
$TST_TMPDIR, thus just restore the order.

Fixes: 1f6bd6e66 ("tst_test.sh: Add $TST_ALL_FILESYSTEMS")

Hi,

I'm sorry for introducing yet another regression in
$TST_ALL_FILESYSTEMS.

Kind regards,
Petr
