[XS] Change in openvpn[master]: Fix extracting IV_MTU

cron2 has submitted this change. ( http://gerrit.openvpn.net/c/openvpn/+/1842?usp=email )

Change subject: Fix extracting IV_MTU
......................................................................

Fix extracting IV_MTU

Commit 06ced3fd accidentally broke extracting the MTU from the peer
info while refactoring the code. Before 06ced3fd the code used
iv_mtu as temporary string and extracted the value into client_max_mtu.
The new code never set client_max_mtu and used iv_mtu as integer instead.

Fix this by setting client_max_mtu again with the real MTU value from
the peer.
