Actually there was a bug in FO compensation which I overlooked in last commit.

While fixing bug in PSS index calculation in 334519d1, I made changes in FO calculation as well. This is not nedeed and caused the FO to misbehave. Hence, reverting it.

This functions fills the ULSCH CQI indication message incorrectly. Also,
it should only be triggered when the eNB requests CSI. We disable it
here and a subsequent commit enables it again.
