[PATCH] drm/amdkfd: Fix compile error if HMM support not enabled

[Philip Yang]

Fixes the below if kernel config not enable HMM support

>> drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_queue.c:107:26: error:
implicit declaration of function 'svm_range_from_addr'

>> drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_queue.c:107:24: error:
assignment to 'struct svm_range *' from 'int' makes pointer from integer
without a cast [-Wint-conversion]

>> drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_queue.c:111:28: error:
invalid use of undefined type 'struct svm_range'

Fixes: de165b53c93f ("drm/amdkfd: Validate user queue svm memory residency")
