hostmem-file: Register TYPE_MEMORY_BACKEND_FILE properties as class properties

To do the conversion, the file_backend_class_init() was moved
after the getter/setter functions. The old
file_backend_instance_init() function was removed because it is
not needed anymore.

The NULL errp arguments on the property registration calls were
changed to &error_abort.
