crypto: hisilicon/qm - delete redundant null assignment operations 

mainline inclusion
from mainline-v6.2-rc1
commit 7bbbc9d8
category: feature
bugzilla: https://gitee/com/openeuler/kernel/issues/16VW8E
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7bbbc9d81be588ae4fb28b5b202e4421dbfef197



-------------------------------------------------------------------

There is no security data in the pointer. It is only a value transferred
as a structure. It makes no sense to zero a variable that is on the stack.
So not need to set the pointer to null.
