ovl: fix workdir creation
commit e1ff3dd1ae52cef5b5373c8cc4ad949c2c25a71c upstream.
Workdir creation fails in latest kernel.
Fix by allowing EOPNOTSUPP as a valid return value from
vfs_removexattr(XATTR_NAME_POSIX_ACL_*). Upper filesystem may not support
ACL and still be perfectly able to support overlayfs.
