Here's the interface I think makes sense for fixing this:

       VOP_GETMNTFLAGS(vp)

.. returns the ored-together mount flags of the filesystem vp and any
filesystems vp is stacked on..

implementation for "leaf" filesystems just looks in the vfs structure.

mount_null, etc., or's its bits together with the one of the
underlying vnode..
