Markus Armbruster 3e80f6902c qdev: Convert uses of qdev_create() with Coccinelle
This is the transformation explained in the commit before previous.
Takes care of just one pattern that needs conversion.  More to come in
this series.

The first rule exempts hw/arm/highbank.c, because it matches along two
control flow paths there, with different @type_name.  Covered by the
next commit's manual conversions.

Missing #include "qapi/error.h" added manually.
