net: call swdev fib del for flushed routes

This is essentially the same patch Nicolas Dichtel posted, but was rejected.
The difference here is rather than calling netlink to notify, this patch
calls swdev to del the fib entry.  Without this patch, routes that are flushed,
for example when an interface goes down, the normal route delete paths aren't
called, so we need to hook the flush path so swdev get's called.

Nicolas' patch is here:
