[PATCH 5.15 538/917] drm/amdgpu: fix a potential memory leak in amdgpu_device_fini_sw()

[Greg Kroah-Hartman]

From: Lang Yu <lang.yu@xxxxxxx>

[ Upstream commit a5c5d8d50ecf5874be90a76e1557279ff8a30c9e ]

amdgpu_fence_driver_sw_fini() should be executed before
amdgpu_device_ip_fini(), otherwise fence driver resource
won't be properly freed as adev->rings have been tore down.

Fixes: 72c8c97b1522 ("drm/amdgpu: Split amdgpu_device_fini into early and late")
