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

stable inclusion
from stable-v5.10.155
commit ee356822618ee86cfab8fac1bec0bf66fb98ea2e
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7M5F4

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=ee356822618ee86cfab8fac1bec0bf66fb98ea2e



--------------------------------

commit f645f85a 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.
