We will support arbitrary SYN Cookie with BPF, and then kfunc at TC will preallocate reqsk and initialise some fields that should not be overwritten later by cookie_v[46]_check(). To simplify the flow in cookie_v[46]_check(), we move such fields' initialisation to cookie_tcp_reqsk_alloc() and factorise non-BPF SYN Cookie handling into cookie_tcp_check(), where we validate the cookie and allocate reqsk, as done by kfunc later. Note that we set ireq->ecn_ok in two steps, the latter of which will be shared by the BPF case. As cookie_ecn_ok() is one-liner, now it's inlined.
