        src/sys/dev/dkwedge: dk.c

Log Message:
dk(4): Use config_attach_pseudo_acquire to create wedges.

This way, indexing of the dkwedges array coincides with numbering of
autoconf dk(4) instances.

As a side effect, this plugs a race in dkwedge_add with concurrent
drvctl -r.  There are a lot of such races in dk(4) left -- to be
addressed with more device references.
