dmaengine: at_hdmac: Do not call the complete callback on device_terminate_all

commit f645f85ae1104f8bd882f962ac0a69a1070076dd upstream.

The method was wrong because it violated the dmaengine API. For aborted
transfers the complete callback should not be called. Fix the behavior and
do not call the complete callback on device_terminate_all.

Fixes: 808347f6a317 ("dmaengine: at_hdmac: add DMA slave transfers")
