[Qemu-devel] [PATCH] qom: Introduce object_property_remove()

[Namhyung Kim <namhyung@gmail.com>]

As the object_property_del(), object_property_del_child() and
object_property_del_all() do similar job, factor out the common code
to a new object_property_remove().

It'll also remove unnecessary call to object_property_find() in case
of object_property_del_child() so that we can get rid of the unused
errp argument too.
