>Description:
fhopen() fails with EINVAL on tmpfs (internally speaking, VFS_FHTOVP):

        if (tfh.tf_id >= tmp->tm_nodes_max)
                return EINVAL;

Seems like this was broken ~2.5years ago.   ... nobody noticing this
is funny, considering the fuss there was with the "critical"
importance of nfs export capability in tmpfs.
>How-To-Repeat:
i'll add an atf test soon (it's blocking on an infrastructure issue)
>Fix:
