[Why]
In SRIOV multi-vf, dpm is always disabled, and pm_attr_list won't
be initialized. There will be a NULL pointer call trace after
removing the dpm check condition in amdgpu_pm_sysfs_fini.
BUG: kernel NULL pointer dereference, address: 0000000000000000
RIP: 0010:amdgpu_device_attr_remove_groups+0x20/0x90 [amdgpu]
Call Trace:
<TASK>
amdgpu_pm_sysfs_fini+0x2f/0x40 [amdgpu]
amdgpu_device_fini_hw+0xdf/0x290 [amdgpu]
[How]
List pm_attr_list should be initialized when dpm is disabled.
