isisd: guard against adj timer display overflow
An adjacency should be removed when the holdtimer expires, but if the
system is overloaded we may end up doing it late. In the meanwhile vtysh
will display an incorrect value in the show isis neighbor output, due to
an overflow of the unsigned variable used to display the Holdtime, e.g.:
pe1# show isis neighbor
Area test:
System Id Interface L state Holdtime SNPA

Guard against that by printing an "Expiring" message instead.
