[PATCH] drm/amdkfd: remove set but not used variable 'pdd'

[YueHaibing]

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

drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_process.c: In function restore_process_worker:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_process.c:949:29: warning:
 variable pdd set but not used [-Wunused-but-set-variable]

It is not used since
commit 5b87245faf57 ("drm/amdkfd: Simplify kfd2kgd interface")
