crypto: hisilicon/qm - delete redundant null assignment operations

[ Upstream commit 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.
