ADAPTER_DOMAIN_SUFFIX is an openvpn3 replacement for
DOMAIN, which is used there for split-dns. This option is pushed
by modern Access Server.

This change improves compatibility between OpenVPN
community client and Access Server.

I think this is reasonable for AS compatibility, which is 
desirable.  (Otherwise, I do have some reservation on
"why do we need to work around uncoordinated actions on the 
v3/AS side in the v2 source?")

I have not tested this besides "stare at source" and "compile
with MinGW", but it looks trivially correct enough.

Your patch has been applied to the master and release/2.5 branch.
