Subject: qed: fix assignment of n_rq_elems to incorrect params field
Patch-mainline: v5.9-rc1
Git-commit: 3540669761b8a26cd5a4ffb9b6c737bc8b941f00
References: jsc#SLE-15143

Currently n_rq_elems is being assigned to params.elem_size instead of the
field params.num_elems.  Coverity is detecting this as a double assingment
to params.elem_size and reporting this as an usused value on the first
assignment.  Fix this.

Addresses-Coverity: ("Unused value")
Fixes: b6db3f71c976 ("qed: simplify chain allocation with init params struct")
