qdev: qdev_create(): use error_report() instead of hw_error()

hw_error() is specific for fatal hardware emulation errors, not for
internal errors related to the qdev object/class abstraction or object
initialization.

Replace it with an error_report() call, followed by abort().

This will also help reduce dependencies of the qdev code (as hw_error()
is from cpus.o, and depends on the CPU list from exec.o).
