Btrfs: prohibit a operation of changing acl's mask when noacl mount option used
when used Posix File System Test Suite(pjd-fstest) to test btrfs,
some cases about setfacl failed when noacl mount option used.
I simplified used commands in pjd-fstest, and the following steps
can reproduce it.
------------------------
# cd btrfs-part/
# mkdir aaa
# setfacl -m m::rw aaa <- successed, but not expected by pjd-fstest.
------------------------
I checked ext3, a warning message occured, like as:
setfacl: aaa/: Operation not supported
Certainly, it's expected by pjd-fstest.
So, i compared acl.c of btrfs and ext3. Based on that, a patch created.
Fortunately, it works.
