docbook2mdoc: Last instance of conistent "struct pnode *nc, *nn"

[schwarze]

Log Message:
-----------
Last instance of conistent "struct pnode *nc, *nn" variable naming.
While the previous commit caused no binary change, this one does,
but only because one variable serving two different purposes
is split into two.  Still no functional change.
