Subject: net/tls: Constify base proto ops used for building tls proto
Patch-mainline: v5.7-rc1
Git-commit: f13fe3e60c799e0fce643458b3bb336bf444cd25
References: bsc#1176447

The helper that builds kTLS proto ops doesn't need to and should not modify
the base proto ops. Annotate the parameter as read-only.
