[PATCH 14/46] selinux: One function call less in genfs_read() after null pointer detection

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sat, 14 Jan 2017 17:43:47 +0100

Call the function "kfree" at the end only after it was determined
that the local variable "newgenfs" contained a non-null pointer.
