DHCP6: Delete the eloop event before closing an ia listener socket

This only happens when dhcpcd is running on a specific interface
and can trigger erroneous logs deleting the socket from
kqueue/epoll.
With the prior eloop it could also trigger ia events from a
non related fd if re-used.

Hopefully fixes #596.
