The variable ret is reassigned and the value EINVAL is never used.
Thus, remove the unused assignments.

AFAICT fix should end up with code like this:
if (args->size)
ret = -EINVAL;
else
ret = proto_context_set_persistence(...)
break;
Alternatively move args->size checking into
proto_context_set_persistence to align with set_persistence().
