Sheng Yang 924366d056 bug 13606: Fix releasing of the first IP of second public nic
The problem is remove_first_ip() in ipassoc.sh can't be called more than one.
The call after the first time would result in iptable and ip command failure,
thus result in failure of execution of IpAssocCommand.

Use the same way to detect already disassociated ip address of non-first
IP(remove_an_ip()) to fix the issue.
