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.
