ul_tbf: Fix accessing zeroed block when checking if transfer is complete

The logic checking whether the UL TBF had already been sent all the data
(and hence was marked as finished and requesting UL ACK to be sent) was
not taking into account the case where there was still no valid block
stored, ie. when the first received UL data block was discarded for some
reason (ex: because TLLI was not set during content resolution).
