        sys/miscfs/kernfs/kernfs.h: revision 1.43

Use specfs vnops for specnodes in kernfs.

While here, don't filter out rootdev and rrootdev merely because
they're not cached.

Fixes the elusive /kern/rootdev and /kern/rrootdev nodes, which only
appeared sometimes when they felt like it, and fixes operations on
/kern/rootdev and /kern/rrootdev always returning EOPNOTSUPP.

We didn't seem to have a single PR for these issues but the following
PRs are all relevant:

PR bin/13564
PR kern/38265
PR kern/38778
PR kern/45974
