tcp: Remove remaining declaration of tcp_l2_mh

Use of tcp_l2_mh has been removed in commit 38fbfdbcb95d,
but its declaration and initialization are always in the code.
Remove them as they are useless.

Fixes: 38fbfdbcb95d ("tcp: Get rid of iov with cached MSS, drop sendmmsg(), add deferred flush")
