crypto: hisilicon/debugfs - Resolve the problem of applying for redundant space in sq dump
When dumping SQ, only the corresponding ID's SQE needs to be dumped, and there is no need to apply for the entire SQE memory. This is because excessive dump operations can lead to memory resource waste. Therefor apply for the space corresponding to sqe_id separately to avoid space waste.
