sundance: set carrier status on link change events

Check if the link is available when a changed interrupt has been received and
set the carrier status appropriately.  The code is copied nearly verbatim from
the dl2k module.  The link status could be used in more places in the driver,
but this is enough to get the carrier status reported to userspace.  Fixes
kernel bug #7487:
