drm/amdgpu: Fix acpi device leak in amdgpu_acpi_enumerate_xcc()
amdgpu_acpi_enumerate_xcc() looks up each XCC ACPI device with
acpi_dev_get_first_match_dev(), which takes a reference to the device.
The reference is dropped with acpi_dev_put() after the XCC info is
initialized, but if the kzalloc_obj() allocation of the XCC info fails
the function returns -ENOMEM without releasing the reference, leaking
the last reference to the ACPI device.
Drop the ACPI device reference on the allocation failure path before
returning.
