crypto: hisilicon/qm - update comments to match function

mainline inclusion
from mainline-v6.3-rc1
commit 9b4eb8f8
category: feature
bugzilla: https://gitee/com/openeuler/kernel/issues/16VW8E
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9b4eb8f8b8eccc313663a99904dcfe2660c41b6c

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

The return values of some functions have been modified,
but the comments have not been modified together. The
comments must be updated to be consistent with the functions.

Also move comments over the codes instead of right place
to ensure consistent coding styles.
