NTB: Fix static check warning in perf_clear_test
As pthr->dma_chan can't be NULL in this context, so there is no need to check pthr->dma_chan. Fixes: 99a06056124d ("NTB: ntb_perf: Fix address err in perf_copy_chunk") Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Jiasen Lin <linjiasen@hygon.cn> Signed-off-by: Jon Mason <jdmason@kudzu.us>
