[PATCH] drm/amdgpu: Replace tmp_adev with hive in amdgpu_pci_slot_reset

[Ce Sun]

Checking hive is more readable.

The following smatch warning:
drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:6820 amdgpu_pci_slot_reset()
warn: iterator used outside loop: 'tmp_adev'

Fixes: 8ba904f54148 ("drm/amdgpu: Multi-GPU DPC recovery support")
