Chen RidongandGreg Kroah-Hartman e658f1c133 dmaengine: at_xdmac: avoid null_prt_deref in at_xdmac_prep_dma_memset ...

commit c43ec96e8d upstream.

The at_xdmac_memset_create_desc may return NULL, which will lead to a
null pointer dereference. For example, the len input is error, or the
atchan->free_descs_list is empty and memory is exhausted. Therefore, add
check to avoid this.
