dmaengine: mv_xor_v2: handle mv_xor_v2_prep_sw_desc() error properly
The mv_xor_v2_prep_sw_desc() is called from a few different places in the driver, but we never take into account the fact that it might return NULL. This commit fixes that, ensuring that we don't panic if there are no more descriptors available.
