[2/3] ntdll: While requesting TokenGroups calculate required user buffer size in server

[Dan Kegel]

Doesn't build here:
        reply->user_len = FIELD_OFFSET( TOKEN_GROUPS,
Groups[group_count] ) + sid_size);
token.c: In function ‘req_get_token_groups’:
token.c:1319:87: error: expected ‘;’ before ‘)’ token
token.c:1319:87: error: expected statement before ‘)’ token
