Subject: qede: Fix qedr link update

From: Michal Kalderon <Michal.Kalderon@cavium.com>


[ Upstream commit 4609adc27175839408359822523de7247d56c87f ]

Link updates were not reported to qedr correctly.
Leading to cases where a link could be down, but qedr
would see it as up.
In addition, once qede was loaded, link state would be up,
regardless of the actual link state.
