cephfs: upgrading mount syntax

The old syntax is almost deprecated,and there are reasons to upgrade it - old syntax is lack of fsid(critical for debugging and observability) - mds_namespace is deprecated, it might be inappropriate to continue using it - kernel will try new syntax first and then the old one, it's a waste Signed-off-by: mageekchiu <[email protected]>
