tcp: get rid of two unnecessary u16s in TCP skb flags copying

I guess these fields were one day 16-bit in the struct but
nowadays they're just using 8 bits anyway.

This is just a precaution, didn't result any change in my
case but who knows what all those varying gcc versions &
options do. I've been told that 16-bit is not so nice with
some cpus.
