[PATCH 36/46] selinux: Move an assignment for the variable "rc" in mls_read_range_helper()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sun, 15 Jan 2017 11:22:23 +0100

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.
