Vitaly Prosyak c2a7c53a2c drm/amdgpu: fix software pci_unplug on some chips
[ Upstream commit 4638e0c29a3f2294d5de0d052a4b8c9f33ccb957 ]

When software 'pci unplug' using IGT is executed we got a sysfs directory
entry is NULL for differant ras blocks like hdp, umc, etc.
Before call 'sysfs_remove_file_from_group' and 'sysfs_remove_group'
check that 'sd' is  not NULL.
