btrfs returned the acl info though it was mounted 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
we add a noacl check for btrfs_get_acl() to fix it.
