crypto: hisilicon/debugfs - fix the struct pointer incorrectly offset…

… problem

commit cd26cd6 upstream.

Offset based on (id * size) is wrong for sqc and cqc.
(*sqc/*cqc + 1) can already offset sizeof(struct(Xqc)) length.

Fixes: 15f112f ("crypto: hisilicon/debugfs - mask the unnecessary info from the dump")
