[PATCH AUTOSEL 6.7 81/88] drm/amdgpu: Drop 'fence' check in 'to_amdgpu_amdkfd_fence()'

[Sasha Levin]

From: Srinivasan Shanmugam <srinivasan.shanmugam@xxxxxxx>

[ Upstream commit bf2ad4fb8adca89374b54b225d494e0b1956dbea ]

Return value of container_of(...) can't be null, so null check is not
required for 'fence'. Hence drop its NULL check.

Fixes the below:
drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_fence.c:93 to_amdgpu_amdkfd_fence() warn: can 'fence' even be NULL?
