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

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

Fixes: 15f112f9ce ("crypto: hisilicon/debugfs - mask the unnecessary info from the dump")
