[PATCH] btrfs/029: fix wrong usage of name filter

["Misono, Tomohiro" <misono.tomohiro@jp.fujitsu.com>]

btrfs/029 uses _filter_testdirs() to filter the name of $TEST_DIR and
$SCRATCH_MNT directory.

In this function, it calls both _filter_test_dir and _filter_scratch
concatenated by pipe. Therefore if $TEST_DIR is a prefix of
$SCRATCH_MNT, this filter function gives wrong filtered name for
$SCRATCH_MNT and the test fails.

Fix this by calling _filter_test_dir and _filter_scratch directly.
