tcp: remove redundant checks

tcp_v4_rcv() checks the following before calling tcp_v4_do_rcv():

    goto bad_packet;
if (!pskb_may_pull(skb, th->doff * 4))

if (skb->len < tcp_hdrlen(skb) || ...)
goto csum_err;

A second check can be removed after no_tcp_socket label for same reason.

Same tests can be removed in tcp_v6_do_rcv()

Note : short tcp frames are not properly accounted in tcpInErrs MIB,

net/mlx4_core: Fix build failure introduced by the EQ pool changes

When CONFIG_RFS_ACCEL or SMP aren't set, we fail to build, fix it.

Also, avoid build warning as of unused function on that setup.
