net/tcp: Consistently align TCP-AO option in the header
Currently functions that pre-calculate TCP header options length use
unaligned TCP-AO header + MAC-length for skb reservation.
And the functions that actually write TCP-AO options into skb do align
the header. Nothing good can come out of this for ((maclen % 4) != 0).
Provide tcp_ao_len_aligned() helper and use it everywhere for TCP
header options space calculations.
Fixes: 1e03d32bea8e ("net/tcp: Add TCP-AO sign to outgoing packets")
