[PATCH nf] net/sched: act_ct: set net pointer before publishing flowtable

nf_flow_table_init() adds the flowtable to the global flowtables list.
However, tcf_ct_flow_table_get() sets the table's network namespace only
after that call, leaving a window where the published table has a NULL
namespace pointer.

Set the namespace before calling nf_flow_table_init() so that flowtable
list walkers can rely on it being initialized.
