multimedia/tvheadend cannot service live TV after upgrading v4.2.7

[김종성]

Hi decke,
tvheadend v4.2.7 has a merged commit 3895c923a FreeBSD: Fix recv problem if
no data received, which touches my previous merged commit 0d5c8efee tcp:
fix tcp_socket_dead() for FreeBSD. It makes the FreeBSD port of tvheadend
unable to service live TV, and reverted from the mainline. (f08bbef11
Revert "FreeBSD: Fix recv problem if no data received.") Please apply this
reverting patch:
