ovl: fix workdir creation 



[ Upstream commit e1ff3dd1ae52cef5b5373c8cc4ad949c2c25a71c ]

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.
