[PATCH 33/46] selinux: Move an assignment for the variable "rc" in class_read()
From: SF Markus Elfring

A local variable was set to an error code in one case before a concrete
error situation was detected. Thus move the corresponding assignment into
an if branch to indicate a software failure there.
