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

Browse Source 
commit cd26cd65476711e2c69e0a049c0eeef4b743f5ac upstream.

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")
