[PATCH] s390/pkey: Remove redundant variable initialization

From: Tianjia Zhang
Date: Sun Aug 02 2020 - 07:15:45 EST


In the first place, the initialization value of `rc` is wrong.
It is unnecessary to initialize `rc` variables, so remove their
initialization operation.

Fixes: f2bbc96e7cfad ("s390/pkey: add CCA AES cipher key support")
