[CK] Fix out of bounds modifications caused by negative
 topk_ids in MoeSortingMultiPhaseKernel_P0_v1 (#6242)

## Motivation

Fix sglang randomly crash by filter negative topk ids.

## Technical Details

In sglang expert parallel mode, there may be idle batch (batch=0) fired,
it will reuse batch=1 resource in cuda graph mode. But in topk op, it
will set non used topk ids to -1, in idle batch case, all topk ids are
set to -1. In `MoeSortingMultiPhaseKernel_P0_v1` negative expert id will
cause overwrite somewhere and sglang may randomly crash.
Except idle batch case, if the captured batch sizes are discrete, there
may be -1 of expert id due to the similar logic.
