btrfs/205: Ignore output of chattr command

With newer kernels, containing upstream commit f37c563bab42 ("btrfs:
add missing check for nocow and compression inode flags") chattr would
produce an error :

  /usr/bin/chattr: Invalid argument while setting flags on /media/scratch/foo1

That's due to the aforementioned commit making the checks stricter. This
is not critical for the purpose of the test so it can be safely
ignored.
