[PATCH Vivid SRU] be2net: log link status

[tim.gardner at canonical.com]

From: Ivan Vecera <ivecera at redhat.com>

BugLink: http://bugs.launchpad.net/bugs/1513980

The driver unlike other drivers does not log link state changes. It's
better for an user when asynchronous link states are logged to the system
log.

v3: Changes from v2 discarded as "not necessary"
