Fixing DCHECK in turnport.cc that was broken by refactoring.

"PROTO_TCP + secure bit" was turned into "PROTO_TLS" by this CL:
https://codereview.webrtc.org/2568833002

But a "DCHECK(proto == PROTO_TCP)" wasn't updated to take this into
account.

This somewhat worries me, because I guess it means we have no tests that
exercise TURN over TLS? All we have is "TestTurnTlsTcpConnectionFails", with a
comment "This test should be removed once we have TLS support."
