[PATCH] drm/amdkfd: Drop redundant NULL pointer check in kfd_topology.c

[Srinivasan Shanmugam]

The list has the head node, the NULL pointer check is therefore
superfluous, Hence removed it.

Fixes the below:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_topology.c:1347 kfd_create_indirect_link_prop() warn: can 'gpu_link' even be NULL?
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_topology.c:1428 kfd_add_peer_prop() warn: can 'iolink1' even be NULL?
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_topology.c:1433 kfd_add_peer_prop() warn: can 'iolink2' even be NULL?
