Subject: [PATCH 4.4 44/53] r8152: get default setting of WOL before initializing

From: Hayes Wang <hayeswang@...ltek.com>

[ Upstream commit 9583a3638dc07cc1878f41265e85ed497f72efcb ]

Initailization would reset runtime suspend by tp->saved_wolopts, so
the tp->saved_wolopts should be set before initializing.
