fix encoding error in mbms by regrouping the missing barrier at a single level

The mbms author copied the encoding function to make a new flavor for mbms but he missed to copy the barrier after the asynchronous launch of turbo encode so, data is following process take input regardless it is already ready or not

the fix moves the barrier at a common position between this new mbms feature and the regular DL coding

@lthomas there is some work about threads, is it related to mbms?

Also I see that you removed some time measurements about turbo coding. It is not clear to me if it was used or not.

It would have been nice to isolate those two things in separate commits, or even other merge requests, if they are not related to mbms.
