iotests: fix _check_o_direct

Unfortunately commit "iotests: handle tmpfs" breaks running iotests
with -nbd -nocache, as _check_o_direct tries to create
$TEST_IMG.test_o_direct, but in case of nbd TEST_IMG is something like
nbd+unix:///... , and test fails with message

  qemu-img: nbd+unix:///?socket[...]test_o_direct: Protocol driver
    'nbd' does not support image creation, and opening the image
    failed: Failed to connect to '/tmp/tmp.[...]/nbd/test_o_direct': No
    such file or directory

Use TEST_DIR instead.
