drm/amdgpu: Fix memory leak in amdgpu_acpi_enumerate_xcc()

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: Fix memory leak in amdgpu_acpi_enumerate_xcc()

In amdgpu_acpi_enumerate_xcc(), if amdgpu_acpi_dev_init() returns -ENOMEM,
the function returns directly without releasing the allocated xcc_info,
resulting in a memory leak.

Fix this by ensuring that xcc_info is properly freed in the error paths.

Compile tested only. Issue found using a prototype static analysis tool
and code review.
