[PATCH AUTOSEL 4.19 061/252] drm/amdgpu: remove set but not used variable 'invalid'

[Sasha Levin]

From: yu kuai <yukuai3@xxxxxxxxxx>

[ Upstream commit 9e089a29c696d86d26e79737bafbce94738fb462 ]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c: In function
âamdgpu_amdkfd_evict_userptrâ:
drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c:1665:6: warning:
variable âinvalidâ 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'

Fixes: 5ae0283e831a ("drm/amdgpu: Add userptr support for KFD")
