Subject: crypto: caam/qi2 - remove redundant assignment to ret
Git-commit: c31b4adee161caa7424febee222d99984008bfa2
Patch-mainline: v5.9-rc1
References: jsc#SLE-16106

The variable ret is being assigned a value that is never read, the
error exit path via label 'unmap' returns -ENOMEM anyhow, so assigning
ret with -ENOMEM is redundamt.

Addresses-Coverity: ("Unused value")
