e1000e: Fix check_for_link return value with autoneg off
[ Upstream commit 4e7dc08e57c95673d2edaba8983c3de4dd1f65f5 ]
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.
Fixes: 19110cfbb34d ("e1000e: Separate signaling for link check/link up")
