openvpn.c: Avoid -Waddress warnings with MinGW 

This happens on newer MinGW versions:
openvpn.c:176:19: error: the comparison will always
evaluate as ‘false’ for the pointer operand in
‘flags + -1’ must not be NULL [-Werror=address]

Strictly speaking this is a false positive, but
the pointer handling is a bit weird, so make the
code more straight-forward.
