Current code of btrfs-convert have a bug of thread conflict, which caused
invalid memory accessing between threads, and make program panic.
This patch add a test item for above bug, as:
# ./misc-tests.sh

[TEST] 002-uuid-rewrite
[TEST] 003-zero-log

#
Note that this bug is not happened every time, especilly in slow
device as loop(slow cpu with fast block device is likely to trigger).
I set loop count to 20 to make bug happened in 90% tests.
