Subject: [PATCH 1/3 net-2.6.26] Remove unnecessary check for opt->is_data in ip_options_compile.

There is the only way to reach ip_options compile with opt != NULL:

ip_options_get_finish
    opt->is_data = 1;
    ip_options_compile(opt, NULL)

So, checking for is_data inside opt != NULL branch is not needed.
