interfaces: on forceful IPv6 reload do not lose the event handling #6637

Browse Source 
User log reveals that this does happen on bootup.  Actual flow:

    kernel - >>>> Invoking start script 'beep'
    opnsense 6735 /usr/local/etc/rc.newwanipv6: dhcpd_radvd_configure(auto) found no suitable IPv6 address on igb1_vlan10
    dhcp6c 25775 dhcp6c_script: REQUEST on pppoe0 executing
    dhcp6c 29279 dhcp6c_script: REQUEST on pppoe0 renewal
    opnsense 30070 /usr/local/etc/rc.newwanipv6: Lost a forceful reload on WAN[wan]) due to previous lock

Since the IPv6 has reloaded the addresses are back to tentative state.
This commit may create a chain of forceful reloads, but that's nothing
that the system didn't try to attempt previously.
