Btrfs: Don't return acl info when mounting with noacl option
Steps to reproduce:
# mkfs.btrfs /dev/sda2
# mount /dev/sda2 /mnt
# touch /mnt/file0
# setfacl -m 'u:root:x,g::x,o::x' /mnt/file0
# umount /mnt
# mount /dev/sda2 -o noacl /mnt
# getfacl /mnt/file0
...
user::rw-
user:root:--x
group::--x
mask::--x
other::--x
The output should be:
user::rw-
group::--x
other::--x
