[PATCH 21/46] selinux: Two function calls less in range_read() after error detection

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 14 Jan 2017 20:20:15 +0100

Adjust a jump target to avoid two calls of the function "kfree" at the end
after a memory allocation failed for the local variable "rt".
