In amdgpu_get_xgmi_hive(), we should not call kfree() after
kobject_put() as the PUT will call kfree().

In amdgpu_device_ip_init(), we need to check the returned *hive*
which can be NULL before we dereference it.

For SRIOV configuration, host driver control the reset method(either FLR or
heavier chain reset). The host will notify the guest individually with FLR
message if individual GPU within the hive need to be reset. So for guest
side, no need to use hive-&gt;reset_domain to replace the original per
device reset_domain

V1:
The amdgpu_xgmi_remove_device function will send unload command
to psp through psp ring to terminate xgmi, but psp ring has been
destroyed in psp_hw_fini.

V2:
1. Change the commit title.
2. Restore amdgpu_xgmi_remove_device to its original calling location.
   Move psp_xgmi_terminate call from amdgpu_xgmi_remove_device to
   psp_hw_fini.
