crypto: hisilicon/sec - Fix memory leak for sec resource release
[ Upstream commit bba4250757b4ae1680fea435a358d8093f254094 ]
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.
