Hi,
There are several reports of "Fatal error during GPU init" will cause
NULL-deref in amdgpu_device_fini_sw(). Although the NULL-deref is result
instead of reason, this NULL-deref will confuse user.

This is probably because "adev" is not fully initialized when
amdgpu_device_init() failed. Thus subsequent amdgpu_device_fini_sw()
will try to release "adev->reset_domain" and cause NULL-deref.
This patch fixes this problem by guarding the code with an "if".
However, I'm new to this module and I didn't fully understand the code,
so please review my code carefully.
Best Regards,
Zhang Boyang
