Guangshuo Li a9e6aa9949 nvdimm: ndtest: Return -ENOMEM if devm_kcalloc() fails in ndtest_probe() 
devm_kcalloc() may fail. ndtest_probe() allocates three DMA address
arrays (dcr_dma, label_dma, dimm_dma) and later unconditionally uses
them in ndtest_nvdimm_init(), which can lead to a NULL pointer
dereference under low-memory conditions.

Check all three allocations and return -ENOMEM if any allocation fails,
jumping to the common error path. Do not emit an extra error message
since the allocator already warns on allocation failure.
