Change subject: Make --dns options apply for tap-windows6 driver
......................................................................

Make --dns options apply for tap-windows6 driver

When tap-windows6 driver is used, both --dhcp-option and
--dns options are applied with DHCP. When processing --dns options,
we don't set "tuntap_options.dhcp_options" member, which is required
for DHCP string to be sent to the driver. As a result, --dns options
are not applied at all.

Fix by adding missing assignment of tuntap_options.dhcp_options.
