Subject: [PATCH] e1000e: Fix check_for_link return value with autoneg off

commit 4e7dc08e57c95673d2edaba8983c3de4dd1f65f5 upstream.

When autoneg is off, the .check_for_link callback functions clear the
get_link_status flag and systematically return a "pseudo-error". This means
that the link is not detected as up until the next execution of the
e1000_watchdog_task() 2 seconds later.
