[PATCH 2/2] vfs_ceph: add empty ACL callbacks

[Yan, Zheng]

If a vfs module has no ACL callbacks, smbd will use its default ACL
callbacks. These default ACL callbacks operate on local filesytem,
it's clearly wrong for ceph case.

libcephfs does not support ACL yet, so this patch adds ACL callbacks
that do nothing.
