[PATCH] fstests: btrfs/182: Update the comment for the fix

[Qu Wenruo <wqu@suse.com>]

The mentioned fix in btrfs-progs is just a dirty fix, and only works for
the test case, not a generic fix.

The proper kernel fix is submitted by Josef, and it's on the good track to be
merged upstream.
So update the comment to make it less confusing.
