ACPI: bus: Avoid non-ACPI device objects in walks over children

ACPI: bus: Avoid non-ACPI device objects in walks over children

When walking the children of an ACPI device, take extra care to avoid
using to_acpi_device() on the ones that are not ACPI devices, because
that may lead to out-of-bounds access and memory corruption.

While at it, make the function passed to acpi_dev_for_each_child()
take a struct acpi_device pointer argument (instead of a struct device
one), so it is more straightforward to use.
