link_gre6: Fix for changing tclass/flowlabel
When trying to change tclass or flowlabel of a GREv6 tunnel which has
the respective value set already, the code accidentally bitwise OR'ed
the old and the new value, leading to unexpected results. Fix this by
clearing the relevant bits of flowinfo variable prior to assigning the
new value.
