Subject: [PATCH 4.4 06/38] netlabel: fix an uninitialized warning in netlbl_unlabel_staticlist()

From: Paul Moore <paul@...l-moore.com>

[ Upstream commit 1ba86d4366e023d96df3dbe415eea7f1dc08c303 ]

Static checking revealed that a previous fix to
netlbl_unlabel_staticlist() leaves a stack variable uninitialized,
this patches fixes that.
