[ Upstream commit 9e089a29c696d86d26e79737bafbce94738fb462 ]
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c: In function ‘amdgpu_amdkfd_evict_userptr’: drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c:1665:6: warning: variable ‘invalid’ set but not used [-Wunused-but-set-variable]
'invalid' is never used, so can be removed. Thus 'atomic_inc_return' can be replaced as 'atomic_inc'
