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.

Coccinelle script:

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.
