isisd: do not disable circuit on ifdown

when zebra detects that an interface is gone, notify the circuit but do
not disable it - the interface is still configured until it isn't.

Without this fix, removing the interface in the kernel and then removing
the circuit from the configuration would cause an assertion in isis_csm.c:78
