Richard Maw 410a7f15f0 networkd: Clean up pool addresses on link down
When the link comes up it assigns addresses
by checking whether the address is 0.0.0.0,
and if so pulling a new address range out of the pool.

If the addresses aren't removed from the pool when the link goes down
then the set of addresses allocated will grow
until all the local address ranges are exhausted,
while it gets a different IP address every time.

This patch frees the addresses when link config is dropped
to fix the address leak,
and on systems which can expect all interfaces to be brought up or down
in a deterministic order this conveniently makes use the same address each time.
