maillist inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I9GMIW
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev.git/commit/?id=bba4250757b4



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

The AIV is one of the SEC resources. When releasing resources,
it need to release the AIV resources at the same time.
Otherwise, memory leakage occurs.

The aiv resource release is added to the sec resource release
function.
