Regression test for a btrfs issue of resizing 'thread_pool' when
remount the fs.
This regression was introduced by the following linux kernel commit:
btrfs: Added btrfs_workqueue_struct implemented ordered
execution based on kernel workqueue
08a9ff3264181986d1d692a4e6fce3669700c9f8
And it was fixed by the following linux kernel commit:
btrfs: fix crash in remount(thread_pool=) case
800ee2247f483b6d05ed47ef3bbc90b56451746c
Signed-off-by: Xing Gu <gux.fnst@cn.fujitsu.com>

v5->v6: Add a filter to wipe "Performing full device TRIM" and
"Turning ON incompat feature" in common/filter:_filter_mkfs.
v4->v5: Redirect stderr to /dev/null.
v3->v4: Remove the check for a bug message.
v2->v3: Add the regresssion commit in description.
Remove "dmesg -c > /dev/null".
Echo "Silence is golden" to indicate that an empty output
file is expected.
v1->v2: Add the fix commit in description.
Add the check for a bug message.
