Ensure mocks for lla allocator _write in test_agent

The test test_create_dvr_fip_interfaces_for_restart_l3agent_case was
causing a file fip-linklocal-networks to be created when the tests are
run, this patch ensures that the correct part of the LinkLocalAllocator
is patched to prevent this in the test case.
