tcp: align tcp_sock_write_rx group

tcp: align tcp_sock_write_rx group

Stephen Rothwell and kernel test robot reported that some arches
(parisc, hexagon) and/or compilers would not like blamed commit.

Lets make sure tcp_sock_write_rx group does not start with a hole.

While we are at it, correct tcp_sock_write_tx CACHELINE_ASSERT_GROUP_SIZE()
since after the blamed commit, we went to 105 bytes.
